摘　　要：本文针对水轮发电机组的非最小相位特性 ,基于设置过渡过程的思想 ,分析并提出了跟踪时间不随输入信号幅值改变的非线性跟踪—微分器 (TD)。在经典的PID控制器的基础上应用改进的TD设置合理的过渡过程 ,即在信号输入通道和信号反馈通道中引入改进的TD ,有效的减小了非最小相位中的反调。使之用于功率设定值变化的水轮发电机组有功功率控制中 ,仿真结果表明了该方法的有效性。For the non-minimum phase characteristic of hydraulic turbine power set,this paper proposes and analyses the nonlinear tracking-differentiator(TD)with invariable tracking time based on the idea of arranging the transient process.The rational transient process is set by the improving TD based on the classical PID controller,which inducts the improving TD in the input signal channel and the feedback channel it effectively reduces the undershoot of non-minimum phase system.The simulation result shows that it is efficacious for the real power control of hydraulic turbine power.
