Abstract：With regard to the slide-to-turn (STT) aircraft constrained by impact angles, a novel robust design approach for three-dimensional integrated guidance and control (3D-IGC) is put forward. Based on some feasible simplification prin-ciples, one nonlinear mathematical model facing to 3D-IGC design is first deduced. For a class of multi-variable nonlinear system, a robust dynamic inversion control (RDIC) method is proposed by introducing a type of control compensation term. Combined RDIC theory with dynamic surface control (DSC) method, the robust design of 3D-IGC law is finished. Sim-ulation results present that, the proposed 3D-IGC law can guarantee the stable flight and accurate guidance of researched aircraft, and also satisfy the constrained condition of impact angles. Furthermore, it possesses strong robust property against system uncertainties and equivalent disturbances.
