摘要
热力系统中的热工过程大多属于高阶惯性系统。高阶惯性系统是一类多容、变化缓慢的动态系统,对此类系统采用一般的常规反馈控制方法是很难获得令人满意的控制效果的。本文应用IMC系统特性和模型参考自适应控制原理,并参照滞后系统Smith预估控制的方法,提出了控制高阶惯性系统的自适应控制新方法,仿真研究及现场实际运行均获得满意的控制效果。
Thermodynamic process in thermodynamic power system mostly belongs to high order inertia system. High order inertia system is a kind of multicapacity and slow - changing dynamic system. For this kind system, usingconventional feedback control method can hardly obtain satisfactory control effect. This paper proposes a new adaptive control method for high-order inertia system, which applies the characteristic of internal model control （IMC） system and the principle of model reference adaptive control, and refers to the lag system Smith pre-estimated control method. Simulation study and on-site operation obtained satisfactory results.
