Data-driven Sliding Mode Control for MIMO systems and Its Application on Linear Induction Motors

In this paper, a model free adaptive integral sliding mode constrained control (MFAISMCC) is proposed to maintain the flux linkage of a linear induction motor (LIM) while tracking the speed reference. Firstly, the mathematica model of a LIM is given after the electrical analysis. In order to linearize the motor system, the technology of compact form dynamic linearzation (CFDL) is applied. Then, the MFAISMCC is proposed based on the analysed linear model. Furthermore, a novel anti-windup compensator for MIMO systems is proposed in case the actuator is within saturation. The whole closed-system stability is proven by Lyapunov stability method. Finally, some simulation results are given to testify the effectiveness of the proposed method compared with the PID controllers.
