Abstract:

In the induction motor vector control system, the classical current PI regulator which is usually used, when the current frequency increases, the coupling degree of d and q axis current was aggravated, emerges voltage saturation and limits the improvement of the system response speed. A PI regulator of complex vector decoupling control algorithm was proposed, which combined complex vector decoupling control algorithm with Anti-windup control algorithm. The simulation and experimental results showed that the proposed controller can improve the dynamic performance of the motor current and speed stability when the motor was overloaded.
