Abstract: The reliably guaranteed cost control of a class of uncertain descriptor systems is discussed. The definition of reliably guaranteed cost of descriptor systems is given first. Thus, the sufficient and necessary conditions are obtained in terms of linear matrix inequalities(LMI), under which the resultant closed-loop descriptor systems are not only of quadratic stabilization but also the upper bound of the cost function when the systems are working in order. Moreover, another sufficient condition is also derived in terms of LMI, under which, when part of actuators are faulty, the resultant closed-loop descriptor systems can remain the same. Then, a reliably guaranteed cost controller is designed, with a numerical example given to illustrate the design method.
