摘　　要：建立无刷直流电机(BLDCM)数学模型,并利用Matlab/Simulink中的无刷直流电机模块搭建了仿真模型,实现了电流环、转速环和位置模糊自适应控制环的三闭环位置伺服系统的仿真。分析了无刷直流电机系统的动、静态性能,得到了电机运行时的位置和转速响应、相电流和相电动势的仿真波形曲线。仿真结果表明位置控制器采用模糊自适应控制算法,响应快,位置、转速响应无超调,具有较强的自适应和鲁棒性。该模型准确易实现,便于修改和替换,仿真结果为BLDCM控制系统的实现提供参考。Built the mathematical model of the brushless DC motor （BLDCM） and established the simulation model in Matlab/Simulink by using its BLDC module, achieving the test performed on a position servo system of triple closed loops with ctirrent, speed and position self-adaptive fuzzy PID control. The static and dynamic performances of BLDCM were simulated and the position, speed, phase current and phase back electromotive force curves were demonstrated. Through self-adaptive fuzzy control, system response time was shortened ; position and speed responds were both no overshoot and fine self-adapting and robustness were shown. The validity of the model was testified and the simulation results offered a good reference for realizing a BLDCM control system.
