基于OS-LSSVM焦炉集气管压力系统的内模控制

摘要

焦炉集气管压力系统具有纯滞后、非线性以及多变量强耦合的特点,难以建立精确的控制模型,传统的控制策略难以对其进行有效的控制.基于OS-LSSVM(在线稀疏最小二乘支持向量机)内模控制具有模型简单、鲁棒性好等特点.利用OS-LSSVM在线辨识集气管压力逆系统,建立逆模型控制器,该方法具有较高的跟踪精度,良好的抗干扰能力,同时能实现集气管压力的解耦控制.将其应用于焦炉集气管压力的控制具有重要的意义.%The coke oven gas collector pressure system has the characteristics of pure hysteresis,nonlinearity and multivariable strong coupling.It is difficult to establish an accurate control model,and it is difficult to control it effectively by traditional control strategies.The internal model control based on OS-LSSVM (online sparse least squares support vector machine) has the characteristics of simple model and good robustness.The OS-LSSVM is used to identify the gas pipe pressure inverse system online,and the inverse model controller is established in this paper.The method has high tracking accuracy, good anti-interference ability,and can realize structural control of the gas collecting pipe pressure.
