DSP-based variable structure control of switched reluctance motor

This paper analyzes highlight the shortcomings of the nonlinear and variable parameters for switched reluctance motor(SRM), and the advantages of variable structure control systems, presents a control method for SRM based on DSP and variable structure control method, Control system using TMS320F2407 chip, full use of the DSP chip resources and the advantages of sliding mode variable structure control system, the hardware structure is simple, and achieve the speed control of SRM. Experiments show that the variable structure control method has better control of SRM dynamic performance and steady precision, and parameter perturbations and external disturbances has strong robustness.
