Consensus-Based Finite-Time Cooperative Guidance with Field-of-View Constraint

The problem of cooperative guidance of multiple missiles with field-of-view constraint is addressed based on consensus theory. Considering the singularity problem when the second-order consensus algorithm is directly applied to missile guidance, a novel finite-time consensus algorithm with field-of-view constraint is derived and proved. The singularity problem is also avoided. Cooperative guidance law under 2D and 3D engagement is designed using a two-stage guidance scheme. In the first stage, a decentralized guidance law is designed based on the derived finite-time consensus algorithm to provide the latter stage’s desired initial conditions, and proportional navigation guidance law is used in the second stage. The proposed cooperative guidance law requires neither time-to-go estimation nor controllable velocity magnitude. Compared with other two-stage guidance schemes, the proposed cooperative guidance law can provide better initial conditions for the second stage. Numerical simulation and comparison work demonstrate the effectiveness and superiority of the proposed cooperative guidance law.
