Direct field oriented control scheme for space vector modulated AC/DC/AC converter fed induction motor

F. BENCHABANE, A. TITAOUINE, O. BENNIS, K. YAHIA, D. TAIBI

《能源前沿(英文)》 2012年 第6卷 第2期   页码 129-137 doi: 10.1007/s11708-012-0183-0

摘要: This paper investigates a Luenberger flux observer with speed adaptation for a direct field oriented control of an induction motor. An improved method of speed estimation that operates on the principle of speed adaptive flux and current observer has been proposed. An observer is basically an estimator that uses a plant model and a feedback loop with measured stator voltage and current. Simulation results show that the proposed direct field oriented control with the proposed observer provides good performance dynamic characteristics. The induction motor is fed by an indirect power electronics converter. This indirect converter is controlled by a sliding mode technique that enables minimization of harmonics introduced by the line converter, as well as the control of the power factor and DC-link voltage. The robustness of the overall system is studied using simulation for different operating modes and varied parameters.

Assessment of a fuzzy logic based MRAS observer used in a photovoltaic array supplied AC drive

Bhavnesh KUMAR, Yogesh K CHAUHAN, Vivek SHRIVASTAVA

《能源前沿(英文)》 2014年 第8卷 第1期   页码 81-89 doi: 10.1007/s11708-014-0295-9

摘要: In this paper a fuzzy logic (FL) based model reference adaptive system (MRAS) speed observer for high performance AC drives is proposed. The error vector computation is made based on the rotor-flux derived from the reference and the adaptive model of the induction motor. The error signal is processed in the proposed fuzzy logic controller (FLC) for speed adaptation. The drive employs an indirect vector control scheme for achieving a good closed loop speed control. For powering the drive system, a standalone photovoltaic (PV) energy source is used. To extract the maximum power from the PV source, a constant voltage controller (CVC) is also proposed. The complete drive system is modeled in MATLAB/Simulink and the performance is analyzed for different operating conditions.

摘要: 本文研究输入时滞分数阶(0<α<1)奇异系统的观测器控制问题。基于史密斯预测器和逼近误差,有输入时滞的系统近似等价于无输入时滞的系统。进一步地,基于线性矩阵不等式方法,提出基于观测器控制的充要条件。该条件由于包含等式约束,因此是非严格线性矩阵不等式条件,在使用工具箱求解时会遇到一些麻烦。因此,本文改进了基于严格线性矩阵不等式的条件。最后,通过数值算例和直流电机实例说明了基于严格线性矩阵不等式的条件的有效性。

《能源前沿(英文)》 2014年 第8卷 第4期   页码 426-433 doi: 10.1007/s11708-014-0314-x

摘要: In this paper, observer design for an induction motor has been investigated. The peculiarity of this paper is the synthesis of a mono-Luenberger observer for highly coupled system. To transform the nonlinear error dynamics for the induction motor into the linear parametric varying (LPV) system, the differential mean value theorem combined with the sector nonlinearity transformation has been used. Stability conditions based on the Lyapunov function lead to solvability of a set of linear matrix inequalities. The proposed observer guarantees the global exponential convergence to zero of the estimation error. Finally, the simulation results are given to show the performance of the observer design.

摘要: A robust polynomial observer is designed based on passive synchronization of a given class of r Colpitts (FOC) systems with mismatched uncertainties and disturbances. The primary objective of the proposed observer is to minimize the effects of unknown bounded disturbances on the estimation of errors. A more practicable output-feedback passive controller is proposed using an adaptive polynomial state observer. The distributed approach of a continuous frequency of the FOC is considered to analyze the stability of the observer. Then we derive some stringent conditions for the robust passive synchronization using Finsler’s lemma based on the fractional Lyapunov stability theory. It is shown that the proposed method not only guarantees the asymptotic stability of the controller but also allows the derived adaptation law to remove the uncertainties within the nonlinear plant’s dynamics. The entire system using passivity is implemented with details in PSpice to demonstrate the feasibility of the proposed control scheme. The results of this research are illustrated using computer simulations for the control problem of the r chaotic Colpitts system. The proposed approach depicts an efficient and systematic control procedure for a large class of nonlinear systems with the fractional derivative.

Tracking control of robot manipulators via output feedback linearization

FEI Yue-nong, Wu Qing-hua

《机械工程前沿(英文)》 2006年 第1卷 第3期   页码 329-335 doi: 10.1007/s11465-006-0034-y

摘要: This paper presents a robot manipulator tracking controller based on output feedback linearization. A sliding mode perturbation observer (SPO) is designed to estimate unmeasurable states and system perturbations that involve system nonlinearities, disturbances and unmodelled dynamics. The use of SPO allows to input/output linearize and decouple the strongly coupled nonlinear robot manipulator system merely by the feedback of joint angles. The controller design does not need an accurate model of the robot manipulator. Simulation studies are undertaken based on a two-link robot manipulator to evaluate the proposed approach. The simulation results show that the proposed controller has more superior tracking control performance, with payload changing in a wide range, in comparison with a sliding mode controller (SMC) designed based on state feedback linearization with full states available.

High-precision gyro-stabilized control of a gear-driven platform with a floating gear tension device

《机械工程前沿(英文)》 2021年 第16卷 第3期   页码 487-503 doi: 10.1007/s11465-021-0635-5

摘要: This study presents an improved compound control algorithm that substantially enhances the anti-disturbance performance of a gear-drive gyro-stabilized platform with a floating gear tension device. The tension device can provide a self-adjustable preload to eliminate the gap in the meshing process. However, the weaker gear support stiffness and more complex meshing friction are also induced by the tension device, which deteriorates the control accuracy and the ability to keep the aim point of the optical sensors isolated from the platform motion. The modeling and compensation of the induced complex nonlinearities are technically challenging, especially when base motion exists. The aim of this research is to cope with the unmeasured disturbances as well as the uncertainties caused by the base lateral motion. First, the structural properties of the gear transmission and the friction-generating mechanism are analyzed, which classify the disturbances into two categories: Time-invariant and time-varying parts. Then, a proportional-integral controller is designed to eliminate the steady-state error caused by the time-invariant disturbance. A proportional multiple-integral-based state augmented Kalman filter is proposed to estimate and compensate for the time-varying disturbance that can be approximated as a polynomial function. The effectiveness of the proposed compound algorithm is demonstrated by comparative experiments on a gear-drive pointing system with a floating gear tension device, which shows a maximum 76% improvement in stabilization precision.

摘要: 交流永磁同步电机在位置控制中得到广泛应用。然而由于内部不确定性和外部载荷干扰,其性能经常不能满足需求。为提高交流永磁同步电机系统的控制性能,提出一种具有快速响应能力和强鲁棒性的方法。首先,设计一个改进的积分终端滑模控制器,该控制器具有快速滑模面和连续的趋近律。然后采用扩展状态观测器测量内部和外部扰动,从而用前馈补偿方式抵消干扰。与其他滑模控制算法相比,该方法响应快速,并具更强的鲁棒性抵抗系统干扰。同时,控制系统位置跟踪误差能在有限时间内收敛至0。仿真和实验结果表明,该方法具有快速响应和强鲁棒性,并保证高精度控制。

摘要:

本研究针对全球定位系统(GPS)信号受限环境下无人飞行器(UAV)的动态目标跟踪问题,提出了一种在速度观测器下的基于图像的视觉伺服(IBVS)控制方法。该方法通过构建虚拟相机,推导出应用于欠驱动无人飞行器上的简化且解耦的图像动力学模型,并进一步考虑了由于动态目标的不可预测旋转和速度变化所带来的不确定性影响。本研究提出了一种新的图像深度模型,该模型拓展了基于图像的视觉伺服方法的应用范围,使之能够对任意姿态旋转的目标进行跟踪。所提出的深度模型确保了在跟踪旋转目标过程中图像特征的准确性和图像轨迹的平滑性。此外,采用所提出的速度观测器来估计无人飞行器与动态目标之间的相对速度。得益于速度观测器,不再需要对平移速度进行测量,并有效减轻了因使用包含噪声的测量数据导致的控制振荡现象。为了提高抗干扰能力,本研究还设计了一种基于积分的滤波器,用于补偿不可预测的环境干扰。所设计的速度观测器和视觉伺服控制器通过李雅普诺夫方法对其稳定性进行分析。通过对比仿真与多阶段实验验证了所提方法对于动态旋转目标跟踪的稳定性能、抗干扰能力和鲁棒性跟踪能力。

《信息与电子工程前沿(英文)》 2018年 第19卷 第9期   页码 1180-1190 doi: 10.1631/FITEE.1601814

摘要: 提出一种新的由状态反馈控制器和鲁棒控制项组成的混沌同步控制器,采用勒让德多项式补偿不确定性,还考虑截断错误。由于正交函数定理,勒让德多项式可逼近任意小的近似误差的非线性函数。因此,勒让德多项式可取代模糊系统和神经网络来估计和补偿控制系统中的不确定性。勒让德多项式具有比模糊系统和神经网络更少的调整参数,它的调整过程更为简单。与模糊系统的参数类似,使用从稳定性分析获得的自适应规则在线估计勒让德系数。假设主系统和从系统分别是Lorenz混沌系统和Chen混沌系统。安全通信系统需要基于观测器同步,因为主系统通过信道只发送一个状态变量。讨论了使用基于观测器同步获得其他状态变量的方法。仿真结果表明该方法的有效性。与模糊滑模控制器的比较表明,所提的控制器表现出优异的瞬态响应。此外,解释了安全通信问题,并测试了安全通信中控制器的性能。

《能源前沿(英文)》 2020年 第14卷 第4期   页码 836-849 doi: 10.1007/s11708-017-0444-z

摘要: This paper proposes a design of control and estimation strategy for induction motor based on the variable structure approach. It describes a coupling of sliding mode direct torque control (DTC) with sliding mode flux and speed observer. This algorithm uses direct torque control basics and the sliding mode approach. A robust electromagnetic torque and flux controllers are designed to overcome the conventional SVM-DTC drawbacks and to ensure fast response and full reference tracking with desired dynamic behavior and low ripple level. The sliding mode controller is used to generate reference voltages in stationary frame and give them to the controlled motor after modulation by a space vector modulation (SVM) inverter. The second aim of this paper is to design a sliding mode speed/flux observer which can improve the control performances by using a sensorless algorithm to get an accurate estimation, and consequently, increase the reliability of the system and decrease the cost of using sensors. The effectiveness of the whole composed control algorithm is investigated in different robustness tests with simulation using Matlab/Simulink and verified by real time experimental implementation based on dS pace 1104 board.

Time-varying formation tracking for uncertain second-order nonlinearmulti-agent systems

Mao-peng RAN, Li-hua XIE, Jun-cheng LI

《信息与电子工程前沿(英文)》 2019年 第20卷 第1期   页码 76-87 doi: 10.1631/FITEE.1800557

摘要:

Our study is concerned with the time-varying formation tracking problem for second-order multi-agent systems that are subject to unknown nonlinear dynamics and external disturbance, and the states of the followers form a predefined time-varying formation while tracking the state of the leader. The total uncertainty lumps the unknown nonlinear dynamics and the external disturbance, and is regarded as an extended state of the agent. To estimate the total uncertainty, we design an extended state observer (ESO). Then we propose a novel ESO based time-varying formation tracking protocol. It is proved that, under the proposed protocol, the ESO estimation error and the time-varying formation tracking error can be made arbitrarily small. An application to the target enclosing problem for multiple unmanned aerial vehicles (UAVs) verifies the effectiveness and superiority of the proposed approach.
