Abstract
A weapon stabilization system for an unbalanced gun tube pivotally mounted on a tank turret or other movable platform is disclosed. The system includes a muzzle position controller which accounts for flexion of the gun tube and which comprises a muzzle reference sensor and a muzzle deflection feedback circuit. The muzzle reference sensor provides a signal indicative of deflections of the gun tube. The muzzle deflection feedback circuit is responsive to this signal to adjust the position of the gun tube in a manner that accounts for the deflections of the gun tube. The gun tube is positioned using a hydraulic actuator with pressure feedback to the stabilization system. The system includes a feedforward controller to compensate for the positive pressure feedback due to dynamic external accelerations acting on the unbalanced gun tube. The feedforward controller comprises one or more sensors that detects these accelerations and a feedforward circuit responsive to the sensors to compensate for the positive feedback. The system further includes a rotational acceleration feedback controller that uses the sensors to provide a damping feedback signal that is related to the rotational acceleration of the gun tube.
