Abstract

An optimal preview controller based on the discrete-time H_∞ control is presented. The preview controller is synthesized by considering the bounded unknown disturbances as well as previewable commands and disturbances. The controller derivation procedure is analogous to the LQ-based scheme. The designed preview gain matrix has a similar structure as the LQ-based one. As the infinity norm 7 of the transfer function matrix tends to ∞, the preview gains obtained by H_∞ control method approach to the gains by the LQR. The LQ-based preview gains are verified to be subsets of the H_∞,-based preview gains.
