摘　　要：针对火电厂锅炉主汽温系统的大滞后、大惯性、非线性等特点,设计了Fuzzy自调整PID参数的Smith预估主汽温控制系统。运用Matlab对系统在多种工况下进行了仿真,结果表明所设计的控制系统在控制品质、鲁棒性方面明显优于常规的Smith预估控制系统。In order to overcome the large delay、the great inertia and nonlinear of the main stream temperature object in fossil fired power station, a control system based on Fuzzy Self-tuning PID Smith Controller is proposed. Through simulation in various situations using Matlab, it shows that the control quality and robustness of this control system apparently are superior to general Smith prediction control system.
