摘要：

建立了一套完整的电动汽车驱动控制算法，以便在满足电机大转矩启动、高效率运行、宽范
围调速的前提下，使电动汽车的动力自动适应不同的行驶工况。在凸极式永磁 （IPM）同步电机启动、
运行、调速等矢量控制策略的前期研究基础上，整合了面对不同行驶工况的驱动电机控制算法；利用
矢量控制的电压限制和电流限制，在IPM 电机的不同运行区域，在不同控制策略之间，可随工况变化
而相互切换。在电动汽车实际负载、工况条件下，搭建仿真模型和实验平台。结果表明：该切换算法
实现了不同工况对应控制策略的平滑切换条件和控制策略。因而，验证了这种全工况控制策略整合
的有效性和可行性。

Abstract:

A complete set of electric vehicle drive control algorithm was established to make drive
performances automatically adapt to different driving cycles, and to satisfy the requirements of large torque
starting, high efficiency running, and wide range speed operation. The algorithm is based on the prophase
vector control strategy research for start, running and speed adjust for the salient pole permanent magnet (IPM)
synchronous motor using the vector control strategy. The algorithm integrates the drive motor control algorithm
for different driving cycles using vector control voltage limit and current limit with different control strategies
switching following operating modes. A simulation model and an experimental platform were built under
actual load and operating conditions for an electric vehicle. The results show that the algorithm gives a more
smooth switching control strategy corresponding to different working conditions. Therefore, the feasibility and
effectiveness of the control strategy integration are verified under all driving cycles.
