为降低轮毂电机转矩脉动对电动汽车平顺性的影响，提出了开关磁阻电机的控制策略。建立了电机的非线性模型，对电机进行了最优角度控制。针对电机转矩脉动问题，首先在直接转矩分配控制基础上，采用模糊算法对传统PID控制器的参数进行在线整定，其次提出将快速终端滑模控制算法与直接转矩分配相结合的控制策略。仿真结果表明，模糊算法的引入提高了系统的稳定性；而快速终端滑模控制算法不仅提高了系统抗干扰的能力，而且降低了电机的转矩脉动。

For reducing the effects of torque ripple in wheel hub motor on the ride comfort of electric vehi-cles, a control strategy for switched reluctance motor ( SRM) is proposed. A nonlinear model for SRM is set up and the optimum switching angle control is exerted on SRM. As for the issue of motor torque fluctuation, firstly the fuzzy algorithm is used to conduct online tuning on the parameters of conventional PID controller based on direct torque distribution control;then a control strategy combining fast terminal sliding mode algorithm with direct torque alloca-tion is put forward. The results of simulation show that the introduction of fuzzy algorithm enhances the stability of system while the use of fast terminal sliding mode algorithm not only raises the disturbance resistance of system, but also reduces the torque ripple of motor.
