【摘要】 非线性比例积分微分(PID)控制是一种利用非线性跟踪-微分器和非线性组合的方法对线性PID控制器进行改进的新型控制策略,它具有不依赖于被控系统模型的特点,对系统工作点和网络结构的变化具有良好的鲁棒性,而且结构简单、易于实现。在反馈线性化的基础上,将非线性PID理论应用到可控串补(TCSC)的控制器设计中。仿真结果表明:设计的控制器较常规控制器对系统运行具有更好的适应性和鲁棒性。更多还原

【Abstract】 Nonlinear PID(Proportional-Integral-Differential) control is a new type of control strategy,using nonlinear tracking-differentiator and nonlinear configuration to improve the perfor-mance of linear PID control.The controller is independent of the controlled system model and easy to be realized,having valuable robustness about working point.The nolinear PID control is used to design the TCSC(Thyristor-Controlled Series Capacitor) controller based on feedback linearization.Simulation results show that the new controller has better adaptability and robustness.更多还原
