摘要
内嵌式永磁同步电机(IPMSM)在基速以下和基速以上的全速度范围内的动、稳态性和鲁棒性对电动车的运行影响很大。通过设计一种参数自整定的模糊PI控制方法,并在MATLAB/Simulink虚拟环境下建模进行仿真。结果表明:相对于转速环采用固定PI控制,模糊-PI控制器改善了IPMSM伺服调速系统全速度范围的动、稳态性能,对负载变化等外部干扰及电机参数变化具有较强的鲁棒性,从而更适应电动汽车的运行特性。
The dynamic and static characteristics and robustness of the interior permanent magnet synchronous motor(IPMSM)in the full speed range have a great influence on the operation of BEV.A fuzzy PI control method with self tuning parameters was designed and simulated in the virtual environment of MATLAB/Simulink.The results show that compared with the fixed PI control*the fuzzy PI controller improves the dynamic and steady performance of IPMSM servo speed control system in the whole speed range,and has strong robustness to external interference such as load change and motor parameter change,so it is more suitable for the operation characteristics of BEV.
