Fuzzy Adaptive Variable Structure Guidance with Application to Space Interception

The adaptive variable structure guidance (AVSG) is robust to target maneuvers, but apt to induce unwanted chattering .Fuzzy technique is used to implementthe AVSGfor eliminating chattering ,and then a new guidance method called fuzzy AVSGis produced .The fuzzy AVSGis applied to the space interception problem .Simulationresults demonstratethe effectiveness ofthe new guidance method .
