一种大时滞过程的控制方法

Control method for integral order process with large time delay

针对常见的1阶和2阶含大时滞过程,将分数阶(PD)^γ控制器引入Smith预估控制器,防止了分数阶控制整数阶时产生的静差。半分数阶二自由度控制系统具有良好的跟随性能和抗扰性能。

For common 1-order and 2-order processes with large time delay, a half fractional(PD)^γ controller is introduced to Smith predictor to prevent the static error produced by fractional order controlling integral order. The 2 D control system with the half fractional order shows good tracking and anti-disturbance properties.
