Optimal Cooperative Guidance Law for Salvo Attack: An MPC-Based Consensus Perspective

In this paper, a model-predictive-control (MPC)-based cooperative guidance law is presented to perform a salvo attack against a stationary target, which guarantees that multiple missiles hit the target simultaneously. Inspired by the concept of consensus in the multiagent systems, the impact time coordination is reformulated as a consensus on the ranges and range rates of the missiles, leading to a solution without explicitly exploiting the time-to-go or its estimate. By the virtue of an MPC framework, constraints on the normal acceleration and field-of-view are also addressed, and the finite-horizon optimality is guaranteed. Three numerical simulation cases are provided to demonstrate the effectiveness of the proposed approach.
