A low cost velocity control of double sided LSRM by sliding mode control and PIC18F452

Abstract

This paper presents a low-cost positioning application based on Linear Switched Reluctance Motor (LSRM). The Design, modeling and experimental results of the motor are detailed and presented in this study. The proposed control strategy is based on Sliding Mode Control (SMC) to control the velocity. PIC18F452 and MOSFET inverter are designed and developed for the implementation of the proposed controls strategy. This solution is characterized by its low-cost thing that can help to implement this actuator more frequently in industrial application. The accuracy and quality of the positioning prove the effeteness of the proposed control strategy. Experimental results show a good correspondence with theoretical and simulation studies. It was seen that problems of force and displacement ripples of the LSRM are solved.
