Abstract: Based on the results of Lyapunov inequality and a necessary and sufficient condition of robust stability for generalized periodically time-varying descriptor systems, the robust stability of a closed-loop system under state feedback control is discussed with its necessary and sufficient condition given, and then the design method for a class of state feedback robust controllers is presented. Introducing the definition of quadratic stability and analyzing the relation between quadratic stability and robust stability of the systems, the necessary and sufficient condition of quadratic stability is obtained for generalized periodically time-varying uncertain descriptor systems. A numerical example is given to prove the conclusion drawn from the discussion.
