Abstract
Based on the mathematical model of AC asynchronism motor, a novel method for modeling and simulation of AC asynchronism motor control system in Matlab has been proposed. In Matlab/Simulink, the independent functional blocks, such as Moter model block, Vector control block, Speed controller block, and Hysteresis current controller block etc, have been modeled. By the organic combination of these blocks, the model of control system can be established easily. In the double loop of control system, a PI controller is adopted in the speed loop and a hyteresis current controller is adopted in the current loop. The reasonability and validity have been testified by the simulation results and this novel method offers a new thought way for designing and debugging actual motors.
