摘　　要：为了提高传统电压调节器的自适应能力,改善其动态调节效果,提出了一种新的单神经元自适应PID控制器的改进算法,并将其应用于SVC控制系统的电压调节系统中。误差较大时,K取大值,确保系统响应的快速性;误差较小时,K取小值,确保系统渐趋稳定。采用MATLAB的S-函数编写了该控制器算法的M语言程序,并在MATLAB/simulink环境下进行了仿真实验。仿真结果表明,基于改进单神经元自适应PID电压调节器的控制系统响应速度快,调节时间短,超调量小,系统动态性能及稳态性能良好。In order to increase adaptive capacity of traditional voltage regulator and improve its dynamic regulation effect,a new improved algorithm of single neuron adaptive PID was proposed and applied to voltage regulation system in SVC control system.During the period of regulation system with big errors,big values are selected for K to realize the fast system response.And during the period of regulation system with small errors,small values are selected for K to ensure the system stability.The program of this controller algorithm was written by using S-function and M language in matlab software,and the simulation experiment was carried out in MATLAB/simulink.The simulation results show that the SVC control system based on improved single neuron adaptive PID voltage regulator has faster response speed,shorter regulate time and smaller oscillation,and the system has good static and dynamic performance.
