Abstract
This paper proposes a new H2 output-feedback control with finite multiple measurement information for discrete-time systems with disturbances. This control is called an H2 finite multiple measurement output-feedback control (H2FMMOFC). The new control ascertains the H2 performance for disturbances and the equivalence to the H2 state-feedback control without disturbances on a finite measurement horizon. The boundedness and exponential stability of the proposed H2FMMOFC are also investigated. The gain matrices of the H2FMMOFC are obtained by solving a convex problem utilizing the linear matrix inequality tool. Via a numerical example, the H2FMMOFC is shown to ensure the H2 performance as well as the excellent robustness property against unexpected temporary model uncertainty although the uncertainty is not considered in its design.
