Towards neutral steer and sideslip reduction for four-wheeled electric vehicles

Guisheng ZHAI, Masayuki NAKA, Tomoaki KOBAYASHI, Joe IMAE

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 1,   Pages 16-22 doi: 10.1007/s11465-012-0316-5

Abstract:

This paper proposes an approach to achieving both neutral steer and sideslip reduction for four-wheeled electric vehicles. The control problem is reduced to constructing a servo system tracking appropriate reference input, where the tracking is realized in the framework of ?∞ control. To deal with time-varying vehicle velocity for practical purpose, a gain scheduling strategy is developed to obtain the controller, where the lower and upper bounds of the velocity are used to obtain a polytopic range for the parameters in the system coefficient matrices. A numerical example is given to show validity of the proposed approach.

Observer design for induction motor: an approach based on the mean value theorem

Mohamed Yacine HAMMOUDI,Abdelkarim ALLAG,Mohamed BECHERIF,Mohamed BENBOUZID,Hamza ALLOUI

Frontiers in Energy 2014, Volume 8, Issue 4,   Pages 426-433 doi: 10.1007/s11708-014-0314-x

Abstract: 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.

Output Feedback Control for the Descriptor TS Fuzzy Systems With Pole-placement Constraints

Gao Dan,Cao Yuanyuan

Strategic Study of CAE 2006, Volume 8, Issue 4,   Pages 63-67

Abstract:

The design of dynamic output-feedback controller is investigated for the descriptor fuzzy TS models. By transforming the design problem into the feasible solution problems to a set of linear matrix inequalities, the properly stabilizing output controllers are obtained. The resulting closed-loop system can be ensured to satisfy certain performance index and locate at the required pole-placement region.

Classical state feedback controller for nonlinear systems using mean value theorem: closed loop-FOC of PMSM motor application

Abrar ALLAG,Abdelhamid BENAKCHA,Meriem ALLAG,Ismail ZEIN,Mohamed Yacine AYAD

Frontiers in Energy 2015, Volume 9, Issue 4,   Pages 413-425 doi: 10.1007/s11708-015-0379-1

Abstract: The problem of state feedback controllers for a class of Takagi-Sugeno (T-S) Lipschitz nonlinear systems is investigated. A simple systematic and useful synthesis method is proposed based on the use of the differential mean value theorem (DMVT) and convex theory. The proposed design approach is based on the mean value theorem (MVT) to express the nonlinear error dynamics as a convex combination of known matrices with time varying coefficients as linear parameter varying (LPV) systems. Using the Lyapunov theory, stability conditions are obtained and expressed in terms of linear matrix inequalities (LMIs). The controller gains are then obtained by solving linear matrix inequalities. The effectiveness of the proposed approach for closed loop-field oriented control (CL-FOC) of permanent magnet synchronous machine (PMSM) drives is demonstrated through an illustrative simulation for the proof of these approaches. Furthermore, an extension for controller design with parameter uncertainties and perturbation performance is discussed.

Synchronization of nonlinear multi-agent systems using a non-fragile sampled data control approach and its application to circuit systems Research Article

Stephen AROCKIA SAMY, Raja RAMACHANDRAN, Pratap ANBALAGAN, Yang CAO,caoyeacy@seu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 553-566 doi: 10.1631/FITEE.2200181

Abstract: The main aim of this work is to design a scheme for the criteria for interconnected coupled circuit systems (multi-agent systems, MASs). NFSDC is used to conduct synchronization analysis of the considered MASs in the presence of s. By constructing suitable Lyapunov functions, sufficient conditions are derived in terms of linear matrix inequalities (LMIs) to ensure synchronization between the MAS leader and follower systems. Finally, two numerical examples are given to show the effectiveness of the proposed control scheme and less conservation of the proposed Lyapunov functions.
