Design of an Adaptive Gust Response Alleviation Control System: Simulations and Experiments

Abstract

An adaptive gust response alleviation control system based on fuzzy logic was designed for a large-aspect-ratio and two-control-surface wing model. A state-space model consisting of an elastic wing model, an actuator segment, and a gust segment was established. Time-domain and frequency-domain simulations and analyses were conducted for continuous random gust response alleviation. Experiments and simulations of continuous sinusoidal gust response alleviation were spread out over time and frequency domains. The simulated results agree well with the experimental results. The control system effectively acts on random gusts in simulations. The control system has similar effects on sinusoidal gusts of different frequencies at different flow velocities in the experiments. The alleviation efficiency of sinusoidal gusts is higher than the alleviation efficiency of random gusts, while the range of the wing-tip gust response is the same.
