Linear switched reluctance motor control with PIC18F452 microcontroller


Abstract: This paper presents the simulation, control, and experimental results of the velocity of a double-sided, 6/4-poled, 3-phased, 8 A, 24 V, 250 W, and 250 N pull force linear switched reluctance motor (LSRM). In the simulation and experimental study, the reference velocity is constant depending on the position and time. The velocity versus the position of the translator was controlled with fuzzy logic control (FLC) and proportional-integral (PI) control techniques. The motor was controlled by PI control method with a PIC18F452 microcontroller due to its low cost. The results of the velocity of a translator were compared with the simulation results of the PI control and FLC techniques. It was seen that the PIC18F452 microcontroller is sufficient in the velocity control of the LSRM, and in the FLC method, the force and velocity ripples are lower than in the PI control method.
