This paper first shows the performance limit of gust alleviation controllers without prior gust information. Since control devices, such as elevator, aileron, and thrust, cannot be driven at the same time as their commands are given, the initial acceleration due to wind gust cannot be alleviated with any controllers which do not detect the wind gust a priori. However, if wind gust information is obtained a priori, then the initial acceleration can be suppressed with some controller, which is the second topic of this paper. Designing such controllers is formulated as a design problem of model predictive controllers, which is formulated as a convex Quadratic Programming (QP) problem and is easily solved numerically. Several numerical examples demonstrate the effectiveness of model predictive controllers to suppress the initial acceleration due to wind gust.
