【Abstract】 A high performance fully digital control system for the control of a high power Switched Reluctance Motor (SRM) for mine hoist system has been presented in this paper. Dual processors architecture is adopted in mis system based on high performance Digital Signal Processor (DSP) TMS320F2812 and Micro Controller Unit (MCU) 89C52. Complex Programmable Logic Device (CPLD) EPM7064S instead of some apart devices is used in order to simplify the exterior circuit and improve the reliability of the system. 132KW high power SRM control system is applied successfully to a hoist carrying waste rocks of mine. The results indicate that the speed tracking performance is prompt, anti-disturbance is strong and the current is close to ideal square waveform. The system is fully met the industry need demonstrate that the system is designed reasonably.更多还原
