“…A modified ITCG is put forward in [6], where the time-to-go is estimated more accurately. Considering the field-of-view constraint, a guidance law with constrained impact time is put forward in [7] based on backstepping control, where the interceptor's leading angle is limited within a prespecified range. An ITCG is developed in [8] by the leading angle's polynomial shaping.…”

In this paper, by utilizing fixed-time control technique and a leader-follower control scheme, a three-dimensional (3-D) cooperative guidance law is developed to tackle impact angle constrained simultaneous arrival problem. Firstly, in the line-of-sight (LOS) direction, guidance command for the leader is put forward to make impact time error converge to zero in fixed time such that the leader is capable of reaching the target at prespecified impact time. Then, guidance command for each follower is designed based on information from adjacent interceptors to guarantee each follower's impact time achieves consensus with that of the leader. Secondly, in the azimuth direction and elevation direction of the LOS, guidance commands are put forward to nullify the LOS angular rates within fixed time. Then, the interceptors are able to reach the target with desired impact angles. Meanwhile, the cooperative guidance law's fixed-time convergence is rigorously proved by Lyapunov stability theory. Finally, simulations are given to illustrate the effectiveness of the theorical results.INDEX TERMS Fixed-time control, impact angle constraint, leader-follower control scheme, prespecified impact time, 3-D cooperative guidance.

This paper proposed an optimal time-varying proportional navigation guidance law based on sequential convex programming. The guidance law can achieve the desired impact angle and impact time with look angle and lateral acceleration constraints. By treating the multiconstraints’ guidance problem as an optimization problem and changing the independent variable to linearize the problem and constraints, the original nonlinear and nonconvex problem is transformed into a series of convex optimization problem so that it can be quickly solved by sequential convex programming. Numerical simulations compared to nonlinear programming and traditional analytical guidance law demonstrate the effectiveness and efficiency of the proposed algorithm. Finally, the proposed guidance law is verified to satisfy different impact time periods and impact angle constraints.

The problem of impact time control guidance with field-of-view constraint is addressed based on time-varying sliding mode control. The kinematic conditions that satisfy the impact time control with field-of-view constraint are defined, and then a novel time-varying sliding surface is constructed to achieve the defined conditions. The sliding surface contains two unknown coefficients: one is tuned to achieve the global sliding surface to satisfy the impact time constraint and zero miss distance, and the other is tuned to guarantee the field-of-view constraint. The guidance law is designed to ensure the realization of the global sliding mode. On this basis, the guidance law is modified to a closed-loop structure, and the maximum detection capability of the seeker is utilized to a greater extent. Under the proposed guidance law, neither the small angle assumption nor time-to-go estimation is needed. The guidance command is continuous and converges to 0 at the desired impact time. Simulation results demonstrate the effectiveness and superiority of the proposed guidance law.
