A robust fuzzy controller is designed to stabilize a class of solvable nonlinear descriptor systems with time-varying delay. First, a new modeling and control method for nonlinear descriptor systems is presented with a fuzzy descriptor model. A sufficient condition for the existence of the fuzzy controller is given in terms of a series of LMIs. Then, a less conservative fuzzy controller design ...

In this paper, we discuss the tracking control problem for fractional order descriptor systems. The aim of paper is to find optimal control-state pair satisfying dynamic constraint form a system such that performance index minimized. method solving convert into standard system. Under some particular conditions, explicit formulas which minimize index.

In this paper we give a survey on balanced truncation model order reduction for linear time-invariant continuous-time systems in descriptor form. We first give a brief overview of the basic concepts from linear system theory and then present balanced truncation model reduction methods for descriptor systems and discuss their algorithmic aspects. The efficiency of these methods is demonstrated b...
