Non-singular terminal dynamic surface control based integrated guidance and control design and simulation

- A novel integrated guidance and control (IGC) design model is established, which has a wider scope of application.
- The essence of IGC is summarized.
- A novel non-singular terminal dynamic surface control (NT_DSC) IGC law is designed which can guarantee the missile hits the target with higher accuracy while better satisfying the terminal impact angular constraints. Simulations of comparisons with SMC_DSC IGC law are effectively support this point.

In this paper, a novel cascade type design model is transformed from the simulation model, which has a broader scope of application, for integrated guidance and control (IGC). A novel non-singular terminal dynamic surface control based IGC method is proposed. It can guarantee the missile with multiple disturbances fast hits the target with high accuracy, while considering the terminal impact angular constraint commendably. And the stability of the closed-loop system is strictly proved. The essence of integrated guidance and control design philosophy is reached that establishing a direct relation between guidance and attitude equations by “intermediate states” and then designing an IGC law for the obtained integrated cascade design model. Finally, a series of simulations and comparisons with a 6-DOF nonlinear missile that includes all aerodynamic effects are demonstrated to illustrate the effectiveness and advantage of the proposed IGC method.
