Simulation study of asynchronous motor VC system based on the simplified SVPWM algorithm

Simplified SVPWM algorithm is an algorithm, which chooses the space voltage vector according to the one-to-one relationships between the motor line voltage and the sector of space voltage vector. This algorithm can overcome many disadvantages in the traditional algorithm, for example the complex operation of coordinates rotation, trigonometric function, inverse trigonometric function etc, and make it easy to realize digital control. In the paper, the simulation model of vector Control system is built by using the simplified SVPWM algorithm and is simulated. Simulation results show that the asynchronous motors VC system based on the simplified SVPWM algorithm has better static and dynamic performance, and verify that the algorithm is feasible.
