摘要分析了无刷直流电动机数学模型原理,建立了控制系统的仿真模型,提出了将模糊控制与传统PID算法相结合的变结构控制新方法。仿真结果表明该方法较传统PI控制具有更好的动、静态特性,并有较高的精度和鲁棒性。说明了该方法的正确性和有效性。 Based on the analysis of the principle of the mathematical model of the BLDCM, a novel variable structure control method which combines fuzzy control with PI control is presented. If the input deviation is greater or less than the given value, the fuzzy structure or PI structure is adopted to control the plant. The simulation shows that the proposed method has better dynamic and static characteristic than traditional PI control, and has high precision and robustness.
