The adaptive variable structure guidance (AVSG) is robust to target maneuvers, but apt to induce unwanted chattering. Fuzzy techniques is used to implement the AVSG for eliminating chattering, and then a new guidance method called fuzzy AVSG is produced. Fuzzy AVSGis applied to the space interception problem. Simulation result demonstrates the effectiveness of the new guidance method.
