Study on Output Feedback Robust Stabilization for Uncertain Discrete Linear Systems. The resulting dynamic output feedback compensator ensures that the controlled object can be stabilized for all allowable uncertainties. The sufficient conditions for existence of dynamic output feedback compensator are deduced. Finally, by solving the standard H∞ output feedback control problem for an equivalent linear time-invariant discrete-time system, a system matrix of a dynamic output feedback compensator for a linear time-varying discrete-time discrete-time system is constructed.
