Parallel State Observer-Based Cooperative Guidance
Xilian Zhang, Kunfeng Lu, Zhaolei Wang, Qian Xu, Nan Bai · 2025
This paper introduces a distributed cooperative guidance law that uses a parallel state observer (PSO) in guidance systems, allowing all missiles to intercept a maneuvering target at a specific terminal angle. The use of a parallel state observer, which consists of multiple differentiators connected simultaneously, can improve the fault tolerance of the guidance system. The leader-follower topology is utilized for transmitting information among multiple missiles. The cooperative control algorithm integrates PSO with a nonsingular feedback linearization strategy. Simulation examples are provided to illustrate the effectiveness of the proposed guidance method.
