Adaptive finite-time control of chaos in permanent magnet synchronous motor with uncertain parameters

Abstract

Permanent magnet synchronous motor (PMSM) exhibits chaotic behavior when its parameters are within a certain range which seriously affect the stable work of PMSM. In order to eliminate the chaos, many approaches have been proposed. Most of them considered asymptotic stability of the system, while finite-time stability makes more sense in practice. In addition, parameters of PMSM may be uncertain because of some external factors, then adaptive control is a good method to be considered. In this paper, adaptive finite-time stabilization problem is considered to eliminate the chaos in PMSM system with uncertain parameters. To show the effectiveness of the proposed method, some simulation results are provided.

Fixed‐Time Stability Analysis of Permanent Magnet Synchronous Motors with Novel Adaptive Control

“…In [28], the authors discussed the finite-time stability control of chaotic PMSM system with parameters uncertain. In [29], the authors further considered the finite-time stabilization problem to eliminate the chaos in PMSM by adopting adaptive control.…”

Adaptive Chaos Synchronization Control of Nonlinear PMSM System Using Extended State Observer

“…Lots of control and synchronization schemes have been represented since the discovery of chaotic impact on the motor control performance, such as finite-time control [5,6], unidirectional correlation control [7], sliding mode control [8][9][10][11], linear control [12], dynamic surface control [13,14], optimal control [15], and neural network control [16]. In [5], an adaptive finite-time control method is proposed for PMSM system to suppress the chaos behavior with parameter uncertainties. The uncertain parameters which are caused by external factors can be solved and the chaos in motor can be effectively stabilized.…”

Design and Simulation of PMSM Speed Regulating System Based on SMVSC

“…So the research on the control technology of PMSM is gradually developed [1][2][3][4][5][6].The PID controller has such advantages as simple structure and easy realization. It is one of the most common control technologies in the field of PMSM speed regulating system.…”
