Transverse Flux Linear Switched Reluctance Motor and Its Control System

A transverse flux linear switched reluctance motor (TFLSRM) drive consisting of TFLSRM, DSP-based controller, and novel position sensor, is studied. The mathematic models of the designed motor including the primary side with three-phase windings and the secondary side are established. The novel position sensor that utilizes the salient pole shape of secondary side is proposed to replace the traditional sensor for the purpose of improving system performances. The robust control system using the speed closed-loop with discrete time reaching law control and the current closed-loop with nonlinear conversion function from force to average current is proposed. The DSP-based controller automatically forces the motor operating in forward motoring, braking, and backward motoring between two distance sensors. The experiments aim at testing the novel position sensor, and the dynamic and static performances of the designed drive. The results verify the perfect performances of the novel position sensor and the proposed TFLSRM drive.
