Abstract:

Optimal control theory and principles are employed to determine the upper limit of firing accuracy when aircraft guns are utilized against aerial targets. The optimization criterion adopted to accomplish this end consists of the minimization of the miss distance between a target and expended projectile at a specified time and also of a consideration for the amount of control expended in the process. It is assumed that there is uncertainty in the target position due to atmospheric disturbances, sensor errors, and uncertainty in the applied target control. An adaptation of Kalman filtering techniques is utilized to make a best estimate of future target position, and dynamic programming is used to determine the optimal trajectory to be flown in order to minimize the miss distance of interest. The optimal trajectory is selected by a derived optimal controller. The improvement obtained from using optimal control theory and principles is determined by comparing this method to existing aiming techniques. A recommended extension to the airairmissile case is also incorporated. Author
