Full states coupling design of integrated guidance and control with input saturations

In this paper, adaptive block backstepping control has been investigated for the integrated missile guidance and autopilot with input constraints. The integrated guidance and control model for full states coupling design satisfies the so-called block low-triangular structure. Adaptive block backstepping control methodology is proposed for the MIMO time-varying nonlinear system with input saturation constraints. Considering the effect of the actuator constraint, a smooth function and a Nussbaum type function are introduced for convenience of controller design. The proposed control scheme guarantees the desired interception performance and the stability of the missile dynamics. The 6-DOF simulations have shown the feasibility of the proposed scheme.
