Abstract


This article first details the the modern chopper cascade speed regulation system works , and further derive the transfer function of the chopper DC circuit and asynchronous motor in all aspects of modern cascade speed control system . Charged with the transfer function of the object based on the double-loop control system regulator parameters tuning formula derived parameters of the regulator . Conclusions applied to push the actual motor which , theoretically and experimentally proved the stability of the double-loop control . Double-loop control feedback parameters current and speed detection method . For modern chopper cascade speed dual digital realization of the closed-loop control , describes the main theoretical basis as well as the design of the digital regulator .
