Microcontroller-Based Speed Control Using Sliding Mode Control in Synchronize Reluctance Motor

Abstract

This paper proposes the implementation of integral sliding mode control for a synchronous reluctance motor (SynRM) using microcontroller-based architecture. The technology of microcontroller system has been quite mature, and the price is much cheaper than the conventional dSPACE control system. The integral sliding mode control algorithm is designed for speed control such that it can alleviate the chattering phenomenon in the presence of unmodeled system dynamics and external disturbances. The SMC method, MTC algorithm and PWM calculations are implemented in MSP432 platform. The microcontroller dsPIC30F4011 can process the three-phase PWM output and the motor speed data information. The motor speed data is transferred to the MSP432 using the UART interface. Both microcontroller-based and dSPACE control architectures are implemented and compared. Experimental results show that the proposed method is robust and cheap for speed control of SynRM system.
