摘 要: 為對陽極焙燒爐溫實施準確控制, 將無源性理論與過程控制相結(jié)合, 根據(jù)熱力學(xué)消耗特性以及系統(tǒng)建模領(lǐng)域的行為性方法設(shè)計穩(wěn)定的控制器。控制點的設(shè)置采用分布式結(jié)構(gòu), 不同控制點的控制策略具有相同的結(jié)構(gòu), 同時考慮時間和空間上的分布特性。 仿真實驗以已有的焙燒爐溫度場模型為基礎(chǔ), 動態(tài)地為各個控制點提供設(shè)定值,結(jié)果表明該方法可以非常有效地實現(xiàn)焙燒爐溫度的有效控制。

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.
