摘　　要：研究了电动车驱动用开关磁阻电机的快速启动和节能控制策略。采用基于加速度反馈的启动策略,在启动过程中,实时检测电机的加速度,通过电流和加速度双闭环调节,实现快速启动的目标。同时,根据初始加速度的大小来判断重载程度,以确定相应的电流斩波限值,既满足启动要求,又防止电流峰值过大。在正常调速过程中,采用自适应开通角控制,达到节能的目的。将一台4kW 12/8极开关磁阻电机替代原直流电动机,用于某电动车驱动,试验结果表明:提出的控制策略在工程实践中是可行的,能够使电动车快速启动,高效运行,一次充电行驶里程提高11%。The fast starting and energy saving control strategies of switched reluctance motor for electric vehicle propulsion were studied. Since acceleration feedback control was adopted in the start-up process, the fast starting purpose was realized by utilizing current and acceleration double-loop control scheme. Meanwhile, judging the load level by the initial acceleration in order to ensure the current chopping limit whitch could both meets the requirement of starting and energy saving and avoiding the large peak of current. The adaptive turn-on angle control approach was used during speed regulation, by which the energy saving purpose was achieved. A 4 kW 12-stator pole and 8-roto pole prototype motor was applied to a electric vehicle to replace the DC driving motor, and the experiment results show that the proposed control strategy is feasible in engineering practice because it make the electric vehicle faster starting performance, higher efficiency, more than 11% once charging mileage.
