混合煤气管道多变量系统自抗扰解耦控制

针对煤气混合蝶阀串联系统具有强耦合、不确定性、干扰因素多、非线性等特点,应用自抗扰控制（ADRC）静态解耦和扩张状态观测器（ESO）动态解耦技术,给出一种适用于煤气混合蝶阀串联系统的ADRC解耦设计方案。为提高系统的响应速度,减少计算量,控制系统去掉跟踪微分器（TD）,并且ESO和NF（非线性反馈）采用线性函数的ADRC。仿真结果表明,该控制方案不仅解耦效果优良,而且具有较好的跟踪性能和抗扰动能力。

Active Disturbance Rejection Decoupling Control for Mixed Gas Pipeline Multivariable System

According to the characteristics of gas mixing butterfly valve groups,such as strong coupling,uncertainty,many disturbances and nonlinear,this paper proposed an active disturbance rejection control（ADRC） system based on static decoupling and ESO dynamic decoupling,in order to eliminate the coupling between the loops.The proposed ADRC system only consists of the ESO and NF using linear function instead of normal nonlinear function in order to meet the requirement of rapidity.Simulation results show that the designed controller not only has good decoupling peformance,but also ensures good robustness and adaptability.
