Development of Observer Model for AAA Tracker Response
Abstract
This report describes the development of a mathematical model for gunner's tracking performance in MTQ Mode II tracking task. The Luenberger observer theory is used to design the gunner model which is composed of three elements--a reduced-order observer, a feedback controller, and a remnant element. An important feature of the model is that its structure is simple, hence the computer simulation of anti-aircraft artillery tracking systems using the gunner model requires only a short execution time. A parameter identification program based on the combined least squares curve-fitting method and the modified Gauss Newton gradient algorithm is developed to determine parameters of the model systematically. Model predictions of both azimuth and elevation tracking errors for several target flyby and maneuvering trajectories are shown to be in excellent agreement with the empirical data obtained from simulation experiments conducted at the Aerospace Medical Research Laboratory, Wright-Patterson AFB, Ohio. It is concluded that the antiaircraft gunner model based on the observer theory can be accurately and efficiently used to study AAA weapon effectiveness and aircraft survivability.
