要約

New methods for analysis of robust stability and optimization of discrete output feedback control systems are developed. Sufficient stability conditions of the zero state are formulated with the joint quadratic Lyapunov function for a family of nonlinear systems with uncertain coefficient matrices and a measured output feedback. The solution of a general problem of robust stabilization and evaluation of the quadratic performance criterion for a family of nonlinear discrete systems are proposed. The results application is reduced to solving the system of linear matrix inequalities.
