Research on speed regulation system of induction motor based on slip frequency control

The indirect vector control strategy based on slip frequency is selected in the control system and the factors that influence decoupling control are simulated and discussed. The decoupling effect of the system is simulated and analyzed by Matlab. On this basis, the hardware system experiment platform based on DSP is built and the experiment was carried out on the 11KW asynchronous motor drive experimental platform. The simulation and experiment results show that the decoupling control of torque and flux is realized, the dynamic response of the control system is fast, the overshoot is small, and the steady state precision is high.
