摘　　要：以新型液压型风力发电机组为研究对象,针对风速随机变化引起变量马达转速恒定困难的问题,提出一种基于单神经元PID自适应控制的方法,深入研究单神经元PID自适应控制器参数对变量马达恒转速控制性能的影响。利用AMESim仿真软件建立定量泵-变量马达液压模型,联合MATLAB/Simulink仿真软件进行了仿真研究。仿真结果表明:相比于经典的PID控制方法,单神经元PID自适应控制方法对变量马达恒转速控制具有良好的效果,增强了系统的抗扰动能力,提高了变量马达恒转速输出精度。The variable motor in a new type hydraulic wind turbine cannot maintain constant speed output,which is caused by random change of wind speed.A method based on single-neuron PID adaptive control was proposed for constant speed control of hydraulic type wind turbine.The AMESim software was used to build the hydraulic model of quantitative pump and variable motor,and the simulation was carried out by MATLAB/Simulink.The simulation results validate that the adaptive single-neuron PID control method can be used to enhance the hydraulic system’s ability of anti-disturbance and improve the accuracy of the variable motor constant speed control.
