Dynamic control allocation for reusable launch vehicles
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540) - Trang 92-96
Tóm tắt
Gain-scheduled linear-affine control allocation functions /spl delta//sub c/=F(x)/spl tau//sub c/+/spl delta//sub 0/(x) are inherently inaccurate due to inherent limits of performance of the design process. As a result, online CA correction is required, either in terms of adaptive methods, e.g., system identification, or time-invariant methods, e.g., /spl Hscr//sub /spl infin// control. We investigate the use of LTI compensator methods for dynamic control allocation (DCA). Design issues include closed loop performance and time-scale separation between the closed-loop vehicle dynamics, the autopilot, and the DCA compensator.
