为实现电机自动化控制的自适应性和快速响应性,并提高控制过程对不同工况的泛化能力,提出基于PID控制器的电力运行设备电机自动化控制方法,构建电力运行设备电机的数学模型,融合神经元和PID,构建单神经元PID自适应控制器,通过径向基函数网络实现电力运行设备电机转速误差的非线性逼近,并将其作为单神经元PID自适应控制器的前馈路径,进行电机转速误差的非线性补偿,在控制过程中,不断调整径向基函数网络和单神经元PID自适应控制器的参数,依据参数调整后的单神经元PID自适应控制器反馈路径实现对电机转速误差精准控制。通过实验验证可知,该方法实现的电力运行设备电机转速控制具有较小的运行误差,对电机转速跳变以及突降进行快速反应,快速使得电机转速恢复平稳。

In order to achieve the adaptability and rapid response of motor automation control,and improve the generalization ability of the control process for different working conditions,a PID controller based motor automation control method for power operating equipment is proposed.A mathematical model of the motor for power operating equipment is constructed,and neural elements and PID are fused to construct a single neuron PID adaptive controller.Nonlinear approximation of the motor speed error of power operating equipment is achieved through radial basis function network,and it is used as the feedforward path of the single neuron PID adaptive controller for nonlinear compensation of motor speed error.During the control process,the parameters of the radial basis function network and the single neuron PID adaptive controller are continuously adjusted.Based on the feedback path of the single neuron PID adaptive controller after parameter adjustment,precise control of motor speed error is achieved.Through experimental verification,it is known that the motor speed control of power operating equipment achieved by this method has small operating errors,and can quickly respond to motor speed jumps and sudden drops,quickly restoring stable motor speed.
