Mathematical model of AC three-phase asynchronous motor is analyzed and vector control princi- ple of AC three-phase asynchronous motor is introduced. Modular design method and structural design method are used to develop parameterization simulation model of AC three-phase asynchronous motor with vector control based on MATLAB/SIMULINKV. Input parameters of simulation model are motor rotor target speed and real-time speed, and output parameters of simulation model is motor torque T. Simulation of motor no-load speed changing process and motor constant speed loading process are carried out based on the established simulation model. Simulation results show that the simulation model can calculate motor speed and torque accurately. The parameterized simulation model can be applied to AC three-phase asynchronous motor vector control system simulation research.
