Residual Filter Design of Dynamic Feedback Controller Based on Computational Mathematics Model

Jiqing Zhao, Fang Shen

Abstract


Reformulated principle for designing a fault residual filter for continuous-time linear MIMO system, based on computational mathematics methods, is treated in this paper. The problem addressed can be indicated as an approach given sufficient conditions for stable residual filter design based on Lyapunov function. Based on Lyapunov equation and LMI technique, the paper presents method for design of those dynamic controllers which stabilize a class of linear continuous time MIMO systems. Two linear matrix inequalities are outlined to posses stabile residual filter structure closest to unknown input observer based residual filter. A structural system model example is presented to illustrate properties of proposed design method.


Keywords
