Hypersonic vehicle attitude single-channel controller design based on spatially optimal rotation vector

Abstract

A novel single-channel control method for hypersonic vehicle is developed based on the idea of rigid body spatially optimal rotation vector. A double-loop, single-channel attitude controller, which solved the seriously coupling problem among channels existing in the traditional three-channel attitude control system, is designed under such method. Outer loop tracks attitude angles by motivating vehicle to rotate in terms of spatially optimal vector, while inner loop tracks angular velocity by producing a statement moment vector. Appropriate control system parameters are chosen through 6-DOF simulation. The simulation results show that this single channel attitude controller provides robust tracking of the desired mission angle profiles. © 2011 Springer-Verlag.
