Abstract

Based on the theory of Active Disturbance Rejection Control, aiming at the problem of passive self-guided super-cavitating vehicle intercepting close-range maneuvering targets, a variable-structure terminal guidance law is designed by using the easily obtainable information of the line-of-sight angular rate, combined with the target's maneuver estimated by extended state observer. The guidance law is simulated and analyzed under a typical engagement scenario, with the results showing that it can achieve a better attack effect with little target's maneuver information. The profile of required acceleration command is smooth, which is suitable and necessary for the super-cavitating vehicles.
