Adaptive cooperative guidance with seeker-less followers: A position coordination-based framework

Area of Science:

• Aerospace Engineering
• Control Systems
• Robotics

Background:

• Cooperative guidance for multiple flight vehicles is crucial for coordinated missions.
• Simultaneous target interception presents challenges, especially with limited follower information.
• Existing methods may lack robustness or adaptability in dynamic scenarios.

Purpose of the Study:

• To develop a cooperative guidance strategy for multiple flight vehicles with a leader and seeker-less followers.
• To achieve simultaneous target impact at a desired time, even without target information for followers.
• To ensure robust and adaptive control for coordinated flight maneuvers.

Main Methods:

• A fixed-time convergent guidance law for the leader, incorporating impact time control.
• An adaptive cooperative guidance strategy for followers based on relative positioning to the leader.
• Coordinated position location algorithms for seeker-less follower vehicles.

Main Results:

• The proposed guidance law enables the leader to achieve impact time control.
• The adaptive strategy allows followers to coordinate with the leader for simultaneous interception.
• Simulation results demonstrate satisfactory effectiveness and validate theoretical analysis.

Conclusions:

• The developed cooperative guidance strategy is effective for multiple flight vehicles.
• The approach ensures simultaneous target impact for leader and seeker-less followers.
• The method offers a robust solution for coordinated guidance problems.
