Abstract:

Based on the constructed model of mass moment interception missile, a decoupled linear system is presented by using feedback linearization approach of differential geometry. To meet the demands of the robustness of interception missile and the co-ordination of the three mass control, the double loop method is proposed which consists of innerloop design using linear quadratic regulator (LQR) and outer-loop H_∞ control considering mixed sensitivity problem.
