Fuzzy Gain-Scheduling Control and its Application to Flight Control

摘要

This paper presents a gain-scheduling control using fuzzy logic called Fuzzy Gain-Scheduling (FGS) control. A Linear Parameter-Varying (LPV) system is first represented by a fuzzy model which consists of linear time-invariant systems at selectedoperating points. A FGS controller is constructed as a fullorder observer-based controller. The proposed method was applied to a longitudinal flight control problem in which the plant was regarded as a LPV system; that is, the altitude and the flightvelocity varied. In simulation studies, compared to a conventional LQG controller, the proposed FGS controller showed better control performance over the entire flight region.
