GUARANTEED COST CONTROL OF DISCRETE TIME UNCERTAIN SYSTEMS

摘要

Guaranteed cost control problem is considered and the conventional linear quadratic optimal state feedback design method is applied to find the robust regulator for linear discrete time systems with structured uncertainties in the kind of linearcombination in the parameters. The obtained control is a robust optimal linear state feedback which guarantees global asymptotic stability of the closed loop system and minimizes the maximal performance bound corresponding to a used quadratic criterion.
