摘 要: 为对阳极焙烧炉温实施准确控制, 将无源性理论与过程控制相结合, 根据热力学消耗特性以及系统建模领域的行为性方法设计稳定的控制器。控制点的设置采用分布式结构, 不同控制点的控制策略具有相同的结构, 同时考虑时间和空间上的分布特性。 仿真实验以已有的焙烧炉温度场模型为基础, 动态地为各个控制点提供设定值,结果表明该方法可以非常有效地实现焙烧炉温度的有效控制。

Abstract:Consumption properties of thermodynamics and the behavioral approach to system modeling were used to derive a new stable controller design procedure, in which the passivity theory and process control theory were combined. The controlled points were arranged in a distribution structure. Different points were controlled by the same schedule, and at the same time, the system distribution properties in time and space were considered. Simulation experiments were based on the known thermodynamic model which dynamically provides the set-points for different control loops. The results show good performance of this method for controlling the system of anode baking kiln.
