输入受限下流体网络系统控制器设计

Controller design for fluid network systems under input saturation

摘要:

由于控制的目标是流体的流量,流体网络是一个高阶的非线性系统。以往这方面的工作都是基于多变量线性模型,文中的设计是基于非线性模型。通过引入电路中的图论理论,建立了流体网络控制系统的非线性模型。基于反输入饱和技术,提出了一种反馈线性化的设计方法。综合运用微分包含、控制原理,得到了所设计系统渐近稳定的结论。

Abstract:

Due to the objective of controlling fluid flows, fluid networks are high-order nonlinear systems. Previous efforts on this topic are based on multivariable linear models. The designs presented here are for a nonlinear model. Introducing graph theoretic concepts from circuit theory, a nonlinear model is established for fluid network control systems. Based on anti input saturation technology, a design method of feedback linearization is proposed. Combining differential inclusion and control theory, asymptotic stability of the system is achieved
