<title>Accurate tracking and control for the small and weak point target based on the adaptive control theory</title>

Abstract

According to the character for the point target and the weak and small target of the IR image, the method discerning and detecting the IR weak and small point target is discussed in this paper. The method of the background adaptive forecast is taken to catch the point target and the weak and small target. IT provides the accurate tracking of the IR image target with a good foundation. Meantime the theory of the adaptive control is utilized for analyzing the tracking and control system of IR image emphatically. According to the character and demand of the control system an adaptive fuzzy PID controller for the parameter is researched and designed to realize the accurate track of the point target and the weak and small target of the IR image. Through a large number of the imitation for the practical system the results prove that the adaptive controller is provided with the high controlling precision, high speed response and the satisfactory robustness.
