【Abstract】 A new AC speed control system-decoupling variable structure control system is proposed in this paper. The decoupling control theory is applied to the induction motor in order to simplify the mathematical model of the induction motor, and the variable structure control theory may surmount the defective result of the variation of the rotor risistor with temperature. A dynamic and static performance can be guaranteed. In this paper, the mathematical model of decoupling variable structure control system, structure of sliding mode controller and simulation results are given.更多还原
