| 摘 要： | 多电机协调控制达到转速一致是电机控制中的一个关键难题,外加负载变动和电机参数变化时会引起电机性能的下降,达不到良好的控制效果。为使电机间保持转速同步,建立了永磁同步电机d-q坐标系下的矢量控制数学模型,基于转速跟随控制,提出一种基于单神经元PID的变增益速度补偿器进行偏差耦合控制。在MATLAB/Simulink建立了3台永磁同步电机的仿真模型。仿真结果表明,与传统PID固定增益速度补偿器算法相比,单神经元PID的变增益速度补偿器具有更强的鲁棒性以及更快的收敛性。

| Abstract: | A key problem in the motor control is to achieve the same speed in the multi-motor coordinated control achieves the same speed. When the load changes and the motor parameters change, the motor performance will be degraded, and will not be reach a desirable control effect. In order to keep the speed between the motors synchronized, the mathematical model of vector control for the permanent magnet synchronous motor d-q coordinate system is established. Based on the speed following control, a variable gain speed compensator based on the single neuron PID is proposed for the deviation coupling control. The simulation model of three permanent magnet synchronous motors is established in MATLAB/Simulink. The simulation results show that compared with the traditional PID fixed gain speed compensator algorithm, the variable gain compensator of single neuron PID has stronger robustness and faster convergence. |
