Resumen
Purpose – This paper aims to determine the optimal preview length for the preview state feedback controller and to design the static preview gains for the controller.
Design/methodology/approach – The design methodology is based on LMI formulations and Bisection Approach to determine the optimal preview length for the preview state feedback controller that achieves robust H∞ performance. The determination of the optimal preview length is such that the performance of the optimized controller is similar (within bounds) to the maximum length controller, in terms of transient and frequency response along with the H∞ performance.
Findings – The proposed algorithm is implemented for two benchmark design examples that verify its ability and applicability. The results show that the optimal preview length controller designed using the proposed method performs similar to the maximum length preview controller (within bounds) and better than reported in literature.
Originality/value – The paper discusses the novel algorithm formulation and its proof as no such method is available to determine the optimal preview length.
