摘要：This paper addresses the design problem of Gain-Scheduled (GS) flight controller for the lateral-directional motions of a research airplane. The GS flight controller, which is scheduled by an inexactly provided scheduling parameter, viz. equivalent air speed measured by Pitot tube, is required to realize model-matching as well as gust suppression under the uncertainties related to onboard actuators. The uncertainty in the provided scheduling parameter is supposed to be represented as neither pure proportional nor pure absolute uncertainties, but as mixed uncertainties of the two types of uncertainties. Two GS flight controllers are designed for our problem; one is designed with the consideration of the uncertainty in the provided scheduling parameter, and the other is designed with the supposition that exact scheduling parameter is given. Flight tests in real environment well illustrate the practicality and the effectiveness of the former GS controller compared to the latter GS controller.
