开关磁阻电机(SRM)具有较强的非线性，很难建立其准确的数学模型，在传统PID调速控制中难以获得整个调速范围内Kp、KI、KD 3个参数的最优组合。而固定参数的传统PID调节器，不利于系统调速的精准性与抗干扰性。通过分析传统PID调节器3个参数的控制特点，主要针对起动、调速、负载扰动等若干状态下，建立适当的、通用的模糊控制规则，将模糊控制和PID控制相结合，构成SRM的模糊PID转速调节器，实现Kp、KI、KD 3个控制参数的自适应调节，从而获得在整个调速范围内不同负载下较好的调速特性。仿真试验表明，所提出方法避免了固定参数转速调节器的比例积分环节导致的低速、轻载工况下的转速超调与振荡，克服了单纯模糊控制所导致的调速误差。

Switched reluctance motor (SRM) has strong nonlinearity, so it is difficult to establish its accurate mathematical model. In the whole speed range of the traditional PID control, the optimal combination of KP, KI and KD is hardly to obtain. The traditional PID regulator with fixed parameters is not suitable for the accuracy and anti-interference of system speed regulation. In order to solve these problems, the control characteristics of three parameters of traditional PID regulator are analyzed. The appropriate and general fuzzy control rules under several states are established, such as starting, speed regulation, load disturbance, etc. Combined with PID control, a fuzzy PID speed regulator of SRM is formed, which realizes the adaptive adjustment of three control parameters KP, KI and KD. So, the better speed regulation characteristics under different loads in the whole speed regulation range are obtained. The simulation results show that the proposed method avoids the speed overshoot and vibration which is caused by the proportional and integral part of the fixed parameter speed regulator under low speed and light load conditions. Meanwhile, it overcomes the speed regulation error caused by simple fuzzy control.
