Robust Control of Mass Moment Interception Missile Based on H_∞ Performance Characteristics

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. It is proved by simulation results that this method can not only meet the demands of the desired performance characteristics but also ensure robust performance when considering system uncertainties.
