The universal variable frequency speed control system with constant V/f and open-loop speed control, as well as the slip frequency speed closed-loop control system, have basically solved the problem of smooth speed regulation of asynchronous motors. However, when higher requirements are placed on the dynamic and static performance of the speed control system by production machinery, the above system is still slightly inferior to the DC speed control system. The reason is that the control law of the system is derived from the steady-state equivalent circuit and steady-state torque formula of the asynchronous motor, without considering the transition process. The performance of the system in terms of stability, starting, and dynamic torque response at low speeds is not yet satisfactory
