We use the linear matrix inequality (LMI) condition. Linear matrix inequality makes the system to be stable. Moreover, the problem of designing robust state stabilization is to overcome when the proposed Linear Matrix Inequality condition is not satisfied, that the closed- loop or bounded systems are proved to be input-to-state stability.en-USPassivitySingular SystemsISSUncertaintyLinear Matrix InequalityThesis
