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

This article 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 consists of PI speed controller with an inner-loop (SMC). provides reference to the SMC constraints according system requirements in terms maximum current and speed. As discontinuous sign function traditional is replaced by continuous supertwisting function, chattering problem eliminated SMC. Moreover, has robustness interference immunity against nonlinear disturbances BDFIM. Simulation experimental results demonstrate excellent robust tracking performance proposed method.
