摘要：

A robust preview assistant operation method based on a T-S fuzzy model is presented in this paper to deal with the decrease of the tracking performance of a man-machine system caused by pilot manipulation delay and aircraft uncertainty. The pilot-aircraft relationship is modeled as an uncertain input-delay T-S fuzzy system, and the preview control theory is applied to compensate for pilot manipulation delay. Based on the performance indices including tracking error and pilot control burden, the man-machine command tracking problem with model uncertainty is transformed to a fuzzy optimal guaranteed cost control issue, and the linear matrix inequalities which satisfy the convex optimization are deduced. A suboptimal preview controller is designed to overcome the deficiency that the linear matrix inequalities cannot be easily solved because the augmented system dimension increases with the growth of preview steps. Finally, the efficiency of the designed fuzzy preview controller is validated through a pilot model simulation and a flight simulator experiment.
