针对以永磁同步电机为执行机构的位置伺服系统，提出了一种单神经元自适应分数阶PD滋控制器。首先建立了永磁同步电机位置伺服系统的简化模型，然后利用神经元自适应及自学习的能力，将单神经元自适应算法与分数阶控制理论相结合，完成了单神经元自适应分数阶PD滋控制器，选择了3个单神经元分别对分数阶PD滋控制器的3个参数进行在线自适应整定，控制器的参数可以根据系统的偏差进行实时调整。仿真结果表明，本方法可使系统获得更好的跟踪特性、抗扰特性及鲁棒特性。

A method of single neuron adaptive fractional order PDμ controller for PMSM position servo system is proposed in this paper. Firstly,the simplified mathematical model of position servo system is built. Then,using the adaptive and the self-learning ability for neuron,the single neuron adaptive fractional order PDμcontroller is completed by combining the single neuron adaptive algorithm and fractional order control theory. The three single neurons are used to complete the online adaptive turning the three parameters of the fractional order PDμ controller,which are adjusted according to the deviation changes in real time. The simulation results show that,the proposed method has batter tracking characteristics,anti-interference and robustness.
