Blended control system design for agile missile with lateral jets and aerodynamic surfaces

The longitudinal dynamic uncertain model of agile missiles with blended lateral jets and aerodynamic surfaces is established. Then a kind of modularization design scheme is proposed: considering the uncertainties and jet interaction of the blended system, the controller is designed based on the structured singular value synthesis; considering the control constraints of aerodynamic surfaces and lateral jet thrusters, the control allocation is achieved by applying redistributed pseudo inverse (RPI) method. Finally, the simulation results show that the designed blended control system can track the overload command rapidly and accurately, and it has robust performance for model uncertainty and jet interaction, moreover, control allocation between aerodynamic surfaces and lateral thrusters is appropriate, which can avoid the aerodynamic surface deflection saturation.
