摘要：The paper considers the discrete-time H∞control problem for systems involving multiple preview disturbance channels. A necessary and sufficient condition under which the problem is solvable is established. The condition and a desired H∞controller are given based on the solutions of a variant structure H∞Riccati equation and an H∞-like Riccati equation. Both the Riccati equations admit a solution under a smaller level of disturbance attenuation than that required for the existence of a stabilizing solution to the standard H∞Riccati equation and their dimensions are independent of the preview length and the number of the disturbance input channels. Different from the pure single H∞preview control problem, we introduce variant structure disturbances, which is the key for our analysis in the paper. © 2013 TCCT, CAA.
