模糊预估PID控制及其应用

Fuzzy Estimating PID Control and Its Application Study in Super heated Steam Temperature Control System

针对ＰＩＤ控制器难以控制大滞后大惯性过程的问题，提出了模糊预估ＰＩＤ控制方法．将该控制方法应用于锅炉过热汽温控制进行仿真研究，结果表明模糊预估ＰＩＤ控制系统具有优良的控制性能及很强的鲁棒性．

Due to the fact that it is very difficult to control processes with large time delay using PID controller, this paper proposes fuzzy estimating PID control which is implemented by introduced a fuzzy estimator into PID control systems to compensate the effect of the time delay of processes. The simulation for super heated steam temperature control system using fuzzy estimating PID control method is carried out. The results show that the proposed control method is valid.
