| Abstract: | The characteristics of drive system and the several running state of the SRM are introduced first. On the basis of relevant analyses, this paper introduces the control policy-varying angular position chopping voltage control at high speed, fixed the angular position chopping current and chopping voltage con trol at low speed. The design adoptes the double-loop control adjuster to implement the voltage PWM chopping. Aiming at 30 kW experimental switched reluctance motor drive, the hardware circuit and the software flowchart of the controller is designed based on TMS320LF2407A. In the end, the experiment waves of current and voltage of each phase in different speed are gave and analyzed. |
