基于单神经元的永磁同步电机自适应PSD速度控制

为了解决伺服系统电机或负载参数发生变化时对控制带来的影响,提出了一种永磁同步电动机(PMSM)的单神经元自适应速度控制方法,引入速度误差、误差的一次差分及误差的二次差分作为单神经元的输入信号,并设计相应的加权系数和学习规则,给出了单神经元实现的Simulink框图,针对PMSM的矢量控制系统,采用MATLAB进行了单神经元自适应PSD速度控制仿真及电机试验台架的试验验证,仿真和试验结果验证了该方法的可行性。

Study of Permanent Magnet Synchronous Motor Adaptive PSD Speed Control Based on Single Neuron

In order to solve the effects when the motor parameters or the load vary to servo system control performance, a single neuron adaptive speed control method is presented for permanent magnet synchronous motor (PMSM). Speed error, first order difference of speed error and second order diffe-rence of speed error are introduced as the input singles of single neuron with weighting coefficients and learning rule designed and the Simulink block diagram for realizing of single neuron offered. In response to a PMSM vector control system, single neuron adaptive PSD speed control simulation is exe-cuted via MATLAB with experiment verification carried out on PMSM test bed. The simulation and experiment results verify the validity of the control method.
