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．
Aiming at the problem that PID controller is difficult to control large lag and large inertia process, a fuzzy predictive PID control method is proposed. The control method is applied to the boiler superheated steam temperature control simulation study, the results show that fuzzy predictive PID control system has excellent control performance and strong robustness.
