摘要：

Based on the extended state observer (ESO), a robust guidance law for intercepting maneuver target with unknown acceleration is proposed. By using ESO, the total dynamics including internal nonlinear dynamics, coupling terms and unknown target acceleration are accurately estimated and dynamically compensated in feedback, by which dynamic feedback linearization and decoupling control are realized. The numerical simulations show that the guidance law can effectively attenuate chattering of the line-of-sight rate between missile and target and ensure guidance accuracy.
