Development of MTQ Tracker Model and Identification of Model Parameters.
Abstract
This technical report summarizes the development of the observer model for the gunner's tracking performance in anti-aircraft artillery (AAA) systems. The Luenberger observer theory is used to design this gunner model which is composed of an identity observer, a feedback controller and a remnant element. The structure of the observer model is much simpler than that of the optimal control model developed by Kleinman, Baron and Levison. The computer execution time of the AAA system simulation using the observer model is about 15% of that using the optimal control model. Short execution time in the AAA system simulation is one of the main advantages of this model. A parameter identification program based on the least squares curve-fitting method and the Gauss-Newton gradient algorithm is developed to identify systematically the parameter values of this gunner model. The ensemble mean and standard deviation of model predictions for both azimuth and elevation tracking errors are compared with human tracking data obtained from experiments conducted at the Aerospace Medical Research Laboratory, WPAFB, Ohio. Model predictions are in excellent agreement with the empirical data for several aircraft flyby and maneuvering trajectories. It is concluded that this gunner model and the parameter identification program can be used accurately and efficiently in the analysis of AAA effectiveness. (Author)
