Fuzzy sliding mode control for synchronization of multiple induction motors drive

Abstract

In order to achieve high reliability and control precision of multiple induction motors drive systems, a fuzzy sliding mode control (FSMC)-based synchronization control strategy is proposed by combining the FSMC technique with the ring coupling synchronization structure. Also, a fuzzy controller is utilized as a switching control part of the FSMC to attenuate chattering phenomena despite large uncertainties that exist in practical applications. Moreover, the stability analysis of the proposed control strategy is derived by Lyapunov stability theorem. The proposed FSMC-based synchronization scheme possesses several attractive advantages of simple control framework, high control precision, strong robustness to uncertainties, and chattering elimination. Furthermore, the performance of the proposed control strategy is investigated on a four induction motors driving system. The numerical simulation results clearly demonstrate the effectiveness of the proposed FSMC based synchronization strategy for multiple induction motors drive at different operating conditions, and its superiority is indicated by comparison with proportional integral (PI) control and conventional SMC.

Real-time nonlinear speed control of an induction motor based on a new advanced integral backstepping approach

“…The IM mathematical model can be expressed through the system of equations (1) to (6), as below (Sun et al, 2019; Trabelsi et al, 2012)…”

“…But their implementation can be difficult because it requires a considerable computing time. In other studies (Sun et al, 2019; Barambones and Alkorta, 2011; Oliveira et al, 2016), researchers used the sliding mode theory due to its robustness and simplicity to improve the global control. This method offers a remarkable dynamic, except that the problem of chattering remains an inconvenience that may not be mitigated completely.…”
