Integrated Design of Guidance and Control Algorithm Considering Multiple Constraints

Compared with the traditional separately designed guidance and control system, the integrated guidance and control system can directly obtain the rudder Angle command according to the relative motion information of the missile and the motion parameters of the guided rocket, which improves the overall performance of the system and avoids redundant and repetitive design. Based on dynamic surface control, a nonlinear differentiator is introduced to design an integrated guidance control algorithm considering the constraints of miss distance and fall Angle, and the closed-loop stability of the system is proved. Finally, the superiority of the algorithm in dynamic surface convergence accuracy and guidance accuracy is verified by simulation results.
