An adaptive fuzzy logic based control system for rifle stabilization uses a rifle where the barrel is freely pivoted on the stock which is held by the human being firing the rifle who may be shooting from a moving vehicle or helicopter; alternatively, the firing person may have erratic hand or body motion. During a tracking mode, when the target is being sighted in, undesired motion is sensed by position sensors to effectively lock the rifle barrel in alignment with the stock. During a stabilizing mode just before actuation of the trigger to fire the rifle, the barrel is unlocked, inertial rate sensors make the barrel relatively immune to movement of the stock to facilitate the barrel remaining sighted on the tracked target. The fire control system includes a fuzzy logic controller which by a set of inference rules provides for both alignment of the barrel with the stock during tracking and also for stabilization of the barrel just prior to firing.
A fire control system for firing a gun or rifle at a target from a moving platform carrying a human being who is visually tracking in a tracking mode said target by aiming said gun or rifle at said target and actuating the trigger to fire said gun or rifle, or where such human being has erratic hand or body motion, said system comprising:
A fire control system for firing a gun or rifle at a target from a moving platform carrying a human being who is visually tracking in a tracking mode said target by aiming said gun or rifle at said target and actuating the trigger to fire said gun or rifle, or where such human being has erratic hand or body motion, said system comprising:
A fire control system for firing a gun or rifle at a target from a moving platform carrying a human being who is visually tracking in a tracking mode said target by aiming said gun or rifle at said target and actuating the trigger to fire said gun or rifle, or where such human being has erratic hand or body motion, said system comprising:
A fire control method for firing a gun or rifle at a target from a moving platform carrying a human being who is visually tracking in a tracking mode said target by aiming said gun or rifle at said target and actuating the trigger to fire said gun or rifle, or where such human being has erratic hand or body motion, said gun or rifle having a sight, a stock movable by said human being, and a barrel freely mounted on said stock at a loading end with its exit end movable in both azimuth and elevation directions, each over a predetermined angle by actuator means connected between said stock and said barrel for moving said barrel over said predetermined angles, said method comprising the following steps:
