Three-dimensional Time Constrained Super-twisting Sliding Mode Integrated Guidance and Control Method
A novel integrated method of guidance and control is proposed towards three-dimensional time constrained guidance problem of flight vehicles.In order to meet the requirements of time constrained guidance with large leading angle as well as large desired arrival time,a new sliding surface is devised,while the asymptotic convergence of the leading angle during sliding motion is proved.On the basis of the proposed sliding surface,an integrated guidance and control law with finite-time stability is proposed leveraging backstepping and Super-twisted algorithm,which is continuous and guarantees robustness under Lipschitz bounded disturbances.The finite-time convergence is proved by Lyapunov stability theory,and the effectiveness of the method proposed is validated by numerical simulations.
