The Research Of Fully Digital DTC System In Asynchronous Motor Based On DSP

Direct Self-Control(DSC) is a fairly new quality control velocity means for Asynchronous Motor. which can reach high dynamic response of torque control and real-time control.This paper research the mathematical model,flux model and basic frame of based on the Direct Self-Control. This paper introduced the way of vector selection table, by using it, we can realize the schema of DSC.we developd a hardware system based on DSP(TMS320F240)and carried out DSC experimention.the results of the experiment indicated that the system has a good torque response as well as smooth speed response.
