Multiple flight vehicles cooperative guidance law based on extended state observer and finite time consensus theory

An extended state observer based cooperative guidance method is proposed for multiple flight vehicles intercepting a coming maneuver target. The guidance geometry for multiple flight vehicles-target is established, and a cooperative guidance law used multi-agent cooperative control theory is designed for multiple flight vehicles. To deal with the uncertainty of the maneuver target, the target acceleration is considered as a disturbance, which is observed using an extended state observer, and compensated in the guidance law. Simulation results show that the designed extended state observer can estimate the target acceleration accurately, and the proposed cooperative guidance can satisfy the demands for controlling the intercept time, and hence the cooperative interception can be achieved.
