Abstract :
In the traditional SVPWM algorithm the sectors is judged by the complex operation of coordinates rotation, trigonometric function, inverse trigonometric function and so on, it is too complex to realize and control. A simplified SVPWM algorithm is proposed in this paper, and we use it to build the mathematical model of DTC motor drive system and simulate. Simulation results show that the asynchronous motors direct torque control system based on a simplified SVPWM algorithm has better static and dynamic performance.
