Finite-Time and Fault-Tolerant Cooperative Guidance Against Maneuvering Target with Time and Angle Constraints

Abstract

AbstractCooperative guidance of multiple missiles against a non-cooperative target with angle constraint and time constraint is investigated. Firstly, guidance model is constructed from guidance kinematics. Secondly, an exponentially convergent state observer and an extended-state-observer (ESO) are designed respectively to estimate unknown target information. Thirdly, a finite time convergent cooperative guidance law with time constraint is designed in line-of-sight (LOS) direction, and the influence of observation error is considered. Another guidance law with angle constraint is designed in normal LOS direction and the scenario of actuator failure is considered. Finally, the simulation of four missiles cooperatively intercepting a maneuvering target is built to verify the feasibility of the proposed guidance laws.KeywordsCooperative guidanceFinite timeActuator failureState observer
