Study on Traction Induction Motor DSC Theory and Realization of DSC on Two microcomputer

直接力矩控制是交流异步电动机的一种新型的控制方法，本文对异步电动机直接力矩控制的理论基础、控制系统结构以及它与其它控制方法的关系等方面作了一定的研究和讨论。针对２００ｋｍ·ｈ－１电动车组的异步牵引电动机交－直－交牵引变流器的功率逆变器，设计了一种由高速数字信号处理器（ＴＭＳ３２０Ｃ３１）和单片微机（８０Ｃ１９６ＭＣ）构成的双微机控制系统，为实现异步牵引电动机直接力矩的控制创造了条件。

Direct Self Control(DSC) is a new control method for induction AC motor.Here,the DSC theoretical basis,control system structure and its relation with other control methods are studied and discussed.In connection with the power inverter of the traction induction motor's AC DC AC traction converter for 200 km·h -1 electrical carset,a two microcomputer control system composed of high speed Digital Signal Processor(DSP,TMS320C31) and single chip microcomputer (80C196MC)is designed,thus providing the condition for the realization of DSC of traction induction motor.
