Low-cost linear switched reluctance motor: Velocity and position control

This paper presents low-cost velocity and position control of a double-sided linear switched reluctance motor (LSRM). This investigation gives a detailed presentation of modeling, simulation and experimental results as well as open and closed loop controls. In addition, control strategy was achieved by the help of proportional-integrator (PI) controller in order to ensure smooth motion with highly reduced position and force oscillations. For low-cost purposes, PIC18F452 control board and inverter-based MOSFET are used. This simple approach helps to integrate the actuator in high precision industrial applications. Comparison between simulation and experiment results gives a good agreement.
