Observer for Takagi Sugeno descriptor system using a new approach

Abstract

This paper deals with a Luenberger observer for a class of Takagi Sugeno (TS) descriptor systems. This kind of systems represents many fields as chemical, robotics and electrical systems. A new approach is used to study the stability analysis of the Takagi Sugeno descriptor observer system. The state estimation error leads to formulate linear matrix inequalities (LMIs) which solve the observer gains. An example for non linear descriptor system is given to illustrate the effectiveness of the proposed approach.
