Direct torque control characteristic modeling of in-wheel motor
摘要
Abstract
Using in-wheel motor as concrete study subject, the direct torque control (DTC) was proposed to overcome the disadvantages of slow torque response and poor dynamic performance for vector control. Based on the DTC mathematical model of asynchronous motor, in-wheel motor DTC simulation model was established by Matlab/Simulink software. The dynamic performance of in-wheel motor was analyzed through simulation model. Based on dSPACE, in-wheel motor test stand was designed. A performance test for inwheel motor was conducted on the test stand. The simulation and test results show that the torque response of DTC is fast and torque ripple is large only at low speed. The simulation model is suitable to express the dynamic performance of in-wheel motor well. The dynamic performance of DTC can meet the requirement of driving system.关键词
