提出了一种适用于高压直流输电系统的单神经元自适应比例-积分-微分调节器(PID)控制器。该控制器与常规的PID控制器相比,由于参数为在线更新,因而更具自适应性;与单纯的神经网络控制器相比,结构简单。在线训练时间短,因此响应速度要快许多。仿真结果表明谊控制器能够更好地抑制直流线路电流的增长,改善整流侧和逆变侧交流母线电压的电压振荡,并且响应快速。提高了系统的稳定性。
The paper put forward a kind of adaptive PID controller of single neuron for I-IVDC power transmission. Compared with conventional PID control', the parameters of this controller can be updated online and with more adaptability. Compared with shnplc neural network controller, the structure of this controller is sknple, with short time for online traiaing and fast response. The sknuhtion results show that the controller can restrain the increase of DC line current, decrease the voltage vibration of AC bus voltage at rcctification side and inversion side, and improve systcrn stabillity with fast response.
