Robust Output Feedback Control for Discrete-Time Nonlinear Systems: The Finite Time Case
James, Matthew R
Date: December 15 - December 17, 1993
In this paper we present a new approach to the solution of the output feedback robust control problem. We employ the recently developed concept of information state for output feedback dynamic games and obtain necessary and sufficient conditions for the solution to the robust control problem expressed in terms of the information state. The resulting controller is an information state feedback controller and is intrinsically infinite dimensional.
