Regional pole assignment for uncertain delta-operator systems

摘要

The pole assignment in a specified disk by state feedback for uncertain delta-operator systems is studied.By making use of algebra Riccati equations,a sufficient and necessary condition of pole assignment for a kind of parameter uncertain delta-operator system in a specified disk by state feedback is presented.And the design method of state feedback controller is also developed.The proposed method can unify some previous related results of continuous and discrete time systems into the delta framework.The efficiency of the design method is illustrated by a numerical example.
