Optimal output feedback control for systems with inaccessible state variables†

Abstract

Optimal linear control laws require the measurement of each and every state variable. However, in practice it is difficult to measure every state variable, and thus the optimal control is not widely accepted. This paper is concerned with overcoming this difficulty by considering the design of optimal linear regulator systems with some inaccessible state variables. Two methods leading to dynamic feedback control laws in terms of measurable output alone are developed. One of these methods is extended to time-varying problems.
