In response to the actual need for coordinated interception of multiple flight vehicle targets
this paper presents a three-dimensional spatio-temporal coordinative guidance law. Firstly
a leader-follower cooperative guidance law is developed based on the homogeneity theory and the fixed-time stability theory. This law ensures that the relative distance and relative velocity between the follower and the leader converge to a consistent value within a fixed time
respoectively. Furthermore
an upper bound for the convergence time of consistency error is provided to enable the simultaneous interception of multiple flight vehicles. Secondly
a non-singular terminal sliding mode guidance law with fixed time convergence is proposed to intercept the target with a specific collision angle in the normal direction of the line of sight. This law achieves the fixed time convergence of attack angle and mitigates the control saturation problem caused by the singularity of guidance command. Additionally
a fixed-time disturbance observer is introduced to compensate for the effects of the target's maneuvering on the guidance system. This observer performs feedforward compensation for the target acceleration. Finally
the Lyapunov stability theory is employed to prove the fixed-time stability properties of the system. The simulated results show that the proposed guidance law can be used to effectively control multiple aircrafts to attack the maneuvering targets at the same time under the leader-follower framework
and attack the targets at the desired terminal angle.

(in Chinese) DOI: 10.12382/bgxb.2022.1086 http://doi.org/10.12382/bgxb.2022.1086 Aiming at the problem of three-dimensional multiple missiles intercepting a maneuvering target simultaneously, a three-dimensional distributed cooperative guidance law considering time and space constraints. The proposed guidance law is based on fixed-time stable theory and adaptive sliding mode theory. Along the light-of-sight (LOS) direction, an improved robust adaptive cooperative guidance law is presented based on fixed-time consensus, which can drive a group of missiles to attack maneuvering target at a desired impact time without inherent chattering of sliding mode control. Along the direction vertical to the line-of-sight, a robust adaptive guidance law is proposed based on nonsingular fixed-time terminal sliding mode technique, which can drive missiles attack target with desired impact angle and avoid collision between missiles. Through the Lyapunov stability theory, the fixed-time stability of closed-loop system is demonstrated. The simulation results show that the proposed approach can be implemented to intercept maneuvering targets with desired impact time and impact angle.
