摘　　要：针对风力机变桨系统非线性的特点,提出采用单神经元比例–积分–微分(proportional integral differential,PID)进行控制。分析了单神经元PID控制器的特点,建立了数学模型。将单神经元PID算法进行改进,得到改进的单神经元PID控制器。仿真结果表明:2种单神经元PID控制器构成的系统均可实现无超调,具有系统稳定性好的特点;改进单神经元PID控制器较单神经元PID控制器的响应速度更快;2种单神经元PID控制器比常规PID控制器的鲁棒性更强。Due to the nonlinear feature of wind turbine pitch-control system, it is proposed to control wind turbine pitch by single neuron PID controller. On the basis of analyzing the features of single neuron PID controller, a mathematical model for it is built. Improving single neuron PID algorithm, an improved single neuron PID controller is attained. Simulation results show that a non-overshoot control system with good system stability can be implemented by the two single neuron PID controllers; the response speed of the improved single neuron PID controller is faster than that of original single neuron PID controller; the robustness of the two single neuron PID controller is better than that of traditional PID controller.
