Abstract

This paper solves the H2 output feedback control problem for continuous-time descriptor systems. An existence condition of the H2 optimal controller is derived based on the standard model matching technique, and a characterization of the optimal controller is given in terms of the solutions of two generalized algebraic Riccati equations. It turns out that the optimal controller has an observer-based structure well-known in the state-space case, so that the results in this paper are natural extensions of the state-space results to the descriptor systems. A numerical example is also included to show the applicability of the proposed results.

    More recently, the model matching technique has been extended in Takaba and Katayama (1998) to cover the case of a generalized continuous-time system whose TFM may be improper.
