Guaranteed cost decoupling control of bank-to-turn vehicle

Abstract

This study presents a novel solution to the multi-variable coupling attitude control of a bank-to-turn vehicle. This highly widely demanded control task becomes very challenging on the vehicle's rolling capabilities while the vehicle tracks a moving target. To effectively deal with the relevant issues, this study proposes an integrated procedure to design the state-feedback decoupling controller to dynamically reduce the coupling effect. In a methodology based on linear matrix inequality, the tracking guaranteed cost control law combined with the decoupling control is proposed to accommodate the parameter uncertainties without coupling. Finally, a new strategy called augmented tracking guaranteed cost decoupling control scheme is developed to eliminate the static errors. Large cohort of simulated bench tests is provided to validate the feasibility and effectiveness of the proposed approaches. Hopefully these examples will also provide potential users guidelines for their applications.
