Switched Reluctance Motor Direct Torque Control Based On Torque Share Function

This dissertation puts emphasis on the minimization of torque ripple of switched reluctance motor (SRM) , which is help for the development of SRM with lower torque ripple's application.In this dissertation, current situation of torque ripple study for SRM is analyzed, then a nonlinear dynamic simulating model for SRD is established with MATLAB Simulink/PSB. The model lays a foundation for researching SRM's torque ripple strategy .A direct torque control strategy based on torque share function is researched by simulating. The torque share function and speed controller are designed. The results of simulation show the effectiveness of the theoretical analysis. The effect of control parameters (switching angle, chopping frequency) on SRM's torque ripple in voltage chopper control mode is also researched..In this dissertation, the hardware and software for SRM digital control system based on microprocessor 80C196KC are designed. Some experiment results of the prototype operation are given in this dissertation.
