Open loop VVVF control has the disadvantage of low output torque when working at low frequency and poor speed precision at different load conditions.Various performance-improving schemes have been proposed for the basic VVVF control by compensating s

The mathematical model regarding three-phase AC asynchronous electromotor is a high-order, nonlinear and strong-coupling system with multiple variables. It is thereby relatively knotty to control its rotation speed and flux linkage effectively due to

Because of the shortcomings of traditional AC - DC - AC frequency-conversion circuit electrical systems, this thesis tries to design a dual PWM speed control by variable voltage frequency variation (VVVF) control system based on voltage space vector
