A ROBUST MULTI-OBJECTIVE SYNTHESIS APPLIED TO LAUNCHER ATTITUDE CONTROL

摘要

We present in this paper an application of a multi-objective to the control of launcher during the atmospheric flight and at the maximal aerodynamic pressure point. This approach is based on the Cross Standard Form. The goal of this new method is to design control laws with high performances and robustness and to handle various kind of specification. Two principal methods encountered in the literature to solve this problem are either the LQG or H_2 control and the H_∞ method. The interest of our approach is that a non conventional LQG/LTR approach, required to satisfy the performance specification, can be integrated in a more general standard problem.
