Decoupling Control System for Pressure of Gas Collector of Coke Oven

针对焦炉集气管压力控制系统多回路、强耦合、非线性的特点,运用反馈补偿解耦方法对其进行解耦,并利用Matlab/Simulink进行仿真。结果表明,该方法基本上消除了焦炉集气管压力控制系统之间的耦合,较好地解决了具有相互耦合的多座焦炉集气管压力稳定问题。

The control system of gas collector pressure of coke oven is a nonlinearity,close coupling and multiple loop system. According to the characteristics,the method of feedback compensation decoupling is used to solve the coupling problem in this system.The simulation for the method is given by using Matlab/Simulink.The simulation result shows that the method can remove the coupling between gas collector pressures, and solve the problem of gas collector pressure stability control for several coke oven with close coupling characteristics.
