Abstract
In order to improve the control result of three phase motor with power supplied by battery, it uses voltage vector control technology to control the three-phase motor excitation current and the torque current respectively. At the same time, according to the principle of rotor flux oriented, it get the aim of measuring and controlling the vector of three phase motor stator current. The research on the way of achieving the algorithm of the voltage space vector pulse width modulation is detailed introduced. By building the simulating model of three-phase asynchronous motor, it simulates the algorithm. As a result, it shows that the algorithm is reasonable, the control performance is better and application requirements of control for three-phase asynchronous motor with power supplied by battery is satisfied.
