摘　　要：对异步电机矢量控制方法和转子时间常数辨识方法进行了理论研究,在此基础上设计出了一种用数字信号处理器作为控制器核心、适合电动汽车运行工况的电动汽车驱动器。矢量控制算法通过坐标变换把多阶的、强耦合的异步电机系统转换为一个与他励直流电机类似的系统,可以实现对其励磁电流分量和转矩电流分量的分别控制,从而可以通过简单的算法满足电动汽车的运行工况要求。理论分析和实验结果都表明所述系统方案是可行的。The theory of Vector control and rotor time constant estimation of induction machine are analyzed, and a driver adapted to the operating function of electric vehicle is designed. The analysis of theory and the test results prove that the design scheme is feasible. The DSP is the core of the controller. The vector control algorithm is that, by using coordinate transformation, the asynchronous motor system, which is of high order and strong eompling, is converted into another system similar to other-excited DC motor,Therefore,its exciting current component and torque current component can be controlled respectively and thus the operation condition of the electric vehicle can be well met via the simple algorithm.
