A Cascade PI-SMC Method for Matrix Converter-Fed BDFIM Drives

Abstract

This paper proposes a cascade proportional-integral second-order sliding mode control (PI-SMC) method for matrix converter-fed brushless doubly-fed induction machine (BDFIM). The PI-SMC method consists of a PI speed controller with an inner-loop second-order SMC. The PI controller provides a reference to the inner-loop second-order SMC with constraints according to the system requirements in terms of maximum current and speed. As the discontinuous sign function in the traditional SMC is replaced by the continuous super-twisting function, the chattering problem is eliminated for inner-loop second-order SMC. Moreover, the inner-loop second-order SMC has robustness and interference immunity against non-linear disturbances of the BDFIM. Simulation and Experimental results demonstrate the excellent robust tracking performance of the proposed PI-SMC method.

Improvement of Sliding Mode Control Strategy Founded on Cascaded Doubly Fed Induction Generator Powered by a Matrix Converter

“…Furthermore, in the case of synchronous operation mode, the slip is equal to zero and the voltage and current of the second stator have continuous forms as illustrated in Figure 19. Many studies have dealt with DFIG control issues for several applications and many approaches have been proposed [30][31][32][33][34][35]. A very interested work is proposed in [30], where the authors propose SMC and an update of SMC, called terminal SMC to control the output voltage of CDFIG.…”

“…All these works ignore pitch control and the CDFIG is not supplied via an MC. In contrast, authors in [35] use SMC with an MC but for a motor application.…”
