Structure of Discrete-Time H Controller

Waree Kongprawechnona, Shun Ushidab, Hidenori Kimurab

ABSTRACT: This paper is concerned with the investigation of the closed-loop structure of an H control system. It is shown that H controller is represented, like Linear Quadratic Gaussian control, as a pseudo state feedback, that is, a state feedback interconnected with an observer. However, in the H control problem (in particular, discrete-time cases) the control structure is more complicated since we cannot choose the state feedback and the observer independently.
