Vector Control of Electric Vehicle's Alternating Current Drive System

在分析异步电机矢量控制基本方程式的基础上,提出了电动汽车的交流异步电机驱动系统结构形式,设计了交流驱动矢量控制方案,然后基于MATLAB/SIMULINK仿真平台建立了驱动系统的仿真模型。结果表明,采用矢量控制的交流驱动电动汽车具有良好的调速性能。

Based on the analysis of fundamental equations of the asynchronous motor vector control, a construction of the electric vehicle drive system with an asynchronous motor is presented, and a vector control scheme is designed. According to MATLAB/SIMULINK, a simulation model of the drive system is established, and some simulation results are given. The results show that the electric vehicle with AC drive system which adopts the vector control has the excellent performance of speed regulation.
