锅炉汽包水位系统的自适应逆控制

要利用自适应逆控制的自适应性和系统辨识能力，提出了对锅炉汽包水位控制系统的自适应逆控制策略。由被控对象的逆对象组成的局部反馈回路可以有效地克服给水扰动以及汽包水位的另一主要扰动——蒸汽流量的扰动。同时，自适应建模所得的FIR滤波器可以跟踪对象的特性变化，由FIR滤波器所得的逆控制器可以使系统的实际输出在对象特性变化情况下跟踪参考模型的输出。仿真结果显示了自适应逆控制的自适应性和鲁棒性。

Adaptive Inverse Control of Boiler Feedwater Level

A kind of AIC(Adaptive Inverse Control) is proposed on utilizing its adaptiveness and system identification capability. Local feedback loop containing inverse model of controlled object is able to cancel feedwater disturbance and another important one, disturbance from steam flow. Mean while, FIR filter which is given by adaptive modeling process can trace variation of characters of controlled object, and the Inverse Controller obtained from FIR filter make reall; output to be line with that of reference model output. Simulation show its robustness and adaptiveness of AIC.
