摘　　要：关于直流电机优化问题,针对永磁无刷直流电机工作过程中电气参数的非线性、时变特性,影响系统的品质特性。在分析电机模型的基础上,提出采用积分系数、比例系数模糊自整定技术,按照电机理想的起动、稳态和制动过程要求,设计了速度偏差、速度偏差微分、控制器输出和比例因子隶属度函数及相应的模糊控制规则,构成了模糊自适应控制器。经仿真结果表明,设计的控制器对电机负载、电机电气参数大范围扰动具有较强的抑制能力,系统动态响应快、超调小,达到了对电机参数变化的自适应控制目的,并为控制器设计提供参考。The electrical parameters of permanent magnet brushless DC motorPMBLDCM）are non-linear,time-varying in the working process.By analyzing the motor model,the integral and the proportional coefficient of fuzzy self-tuning technology was used to design speed error,speed error differential,the controller output,proportional factor membership function and the corresponding fuzzy control rules according the ideal motor operation requirements.These designed fuzzy rules constituted the fuzzy adaptive controller for the PMBLDCM.The simulation results showed that the designed controller has a strong disturbance restraining capability,fast dynamic response,small overshoot in the motor load and electrical parameters changes in large-scale.The controller has adaptive control ability under motor parameters varying.
