室内散热器供热系统的鲁棒控制
Robust control of room radiator heating system
摘要：
建立了由散热器、阀门、室内空气和围护结构动态模型构成的室内散热器供热系统动态模型，分析了散热器供热系统的稳态与动态特性，提出了鲁棒H∞控制器和鲁棒PI控制器的设计方法，对比分析了这2种控制器的扰动抑制性能。结果表明，这2种控制器都能提高室内供热系统的扰动抑制效果，但鲁棒H∞控制器在稳定性、控制速度、控制精度上都优于鲁棒PI控制器。

Abstract：
Establishes the dynamic model of the room radiator heating system including radiator, valve, indoor air and envelope models. Analyses the static and dynamic performances of the radiator heating system. Presents the design methods of robust H∞ controller and robust PI controller. Compares the disturbance rejection performances of the two controllers. The results show that both two controllers can ensure good disturbance rejection performance, but the robust H∞ controller is better in stability, control velocity and accuracy.
