Reusable boosted vehicle attitude controller design.

Purpose – The purpose of this paper is to develop an attitude control strategy for the reusable boosted vehicle with large angle of attack, and to remove the cross coupling among roll, pitch and yaw channels. Design/methodology/approach – The coordinated gain scheduling control strategy consists mainly of two parts. First, initially ignoring dynamic coupling, single channel gain scheduling controller is designed based on linearized models, respectively. Second, with respect to main channel gain scheduling controller, coordinated scheduling controller is used to generate intentionally cross coupling to partly cancel inter-channel cross coupling of reusable boosted vehicle. Findings – A coordinated gain scheduling control strategy is presented, and no such analytical solution can be found for the reusable boosted vehicle. Practical implications – The design idea of coordinated gain scheduling strategy is straightforward in physical concepts and has great value for engineering applications. Originality/value – Coordinated gain scheduling control strategy is novel in that single channel gain scheduling design does not involve small perturbation linearization and coordinated channel is scheduled.
