Flight test of flight controller for arbitrary maneuverability and wind gust rejection

This paper addresses flight controller design for the following two requirements; the realization of arbitrary maneuverability and the reduction of the motions driven by wind gust. For the lateral-directional motions of a research aircraft, we design a flight controller that satisfies the aforementioned two requirements; the latter is achieved by designing a feedback controller which minimizes H _infin norm from wind gust to controlled outputs and the former is achieved by designing a right inverse system as the feedforward controller for the closed-loop system composed of the plant and the feedback controller. After confirming that the designed controller has good performance in hardware-in-the-loop simulations, i.e. the controller achieves good wind gust rejection and realizes arbitrary maneuverability, we conduct flight tests to verify these performance under real conditions. Flight tests also demonstrate that the controller has good performance for the simultaneous realization of wind gust rejection and arbitrary maneuverability
