Bingxin LI, Xiangfei ZHAO, Xuefeng ZHANG, Xin ZHAO

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 12,   Pages 1862-1870 doi: 10.1631/FITEE.2200294

Abstract: In this paper, for fractional-order with order (0<<1) and is studied. On the basis of the Smith predictor and approximation error, the system with is approximately equivalent to the system without . Furthermore, based on the (LMI) technique, the necessary and sufficient condition of is proposed. Since the condition is a nonstrict LMI, including the equality constraint, it will lead to some trouble when solving problems using toolbox. Thus, the strict LMI-based condition is improved in the paper. Finally, a numerical example and a direct current motor example are given to illustrate the effectiveness of the strict LMI-based condition.

Intelligent fractional-order integral sliding mode control for PMSM based on an improved cascade observer Research Articles

Lingfei XIAO, Leiming MA, Xinhao HUANG,lfxiao@nuaa.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 2,   Pages 328-338 doi: 10.1631/FITEE.2000317

Abstract: In this paper, an intelligent control (FOISMC) strategy based on an improved cascade is proposed. First, an FOISMC strategy is designed to control a . It has good tracking performance, is strongly robust, and can effectively reduce chattering. The proposed FOISMC strategy associates strong points of the integral action (which can eliminate steady-state tracking errors) and the fractional calculus (which is flexible). Second, an improved cascade is proposed to detect the rotor information with a smaller observation error. The proposed combines an adaptive sliding mode and an extended high-gain . In addition, an improved variable-speed grey wolf is designed to enhance controller parameters. The effectiveness of the strategy is tested using simulations and an experiment involving model uncertainty and external disturbance.

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

Frontiers of Mechanical Engineering 2021, Volume 16, Issue 3,   Pages 487-503 doi: 10.1007/s11465-021-0635-5

Abstract: 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.

A fast integral sliding mode controller with an extended state observer for position control of permanent Research Articles

Jun-feng Jiang, Xiao-jun Zhou, Wei Zhao, Wei Li, Wen-dong Zhang,cmeesky@163.com

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 8,   Pages 1119-1266 doi: 10.1631/FITEE.1900298

Abstract: has been widely used in position control applications. Its performance is not satisfactory due to internal uncertainties and external load disturbances. To enhance the control performance of PMSM systems, a new method that has fast response and good robustness is proposed in this study. First, a modified integral terminal is developed, which has a fast-sliding surface and a continuous reaching law. Then, an is applied to measure the internal and external disturbances. Therefore, the disturbances can be compensated for in a feedforward manner. Compared with other sliding mode methods, the proposed method has faster response and better robustness against system disturbances. In addition, the position tracking error can converge to zero in a finite time. Simulation and experimental results reveal that the proposed control method has fast response and good robustness, and enables high-precision control.
