Controlling flight vehicle motion and onboard video camera for tracking a dynamic target

摘要

The problem of controlling a rotary on-board video camera in the process of an unmanned flight vehicle (FV) moving along a given route and simultaneous tracking of a dynamic object is considered. Wind loads affect FV motion and prevent the camera from accurately aiming at the object of observation. We consider a general intelligent control scheme of FV motion that realizes a set of behavioral strategies simulating actions of the human operator in a disturbed environment. Block diagrams of automatic control systems of the aircraft and onboard video camera are offered. The mathematical models of FV, video camera and the wind disturbances are determined by transfer functions and integrated into a single simulation system “FV - video camera”. In the experimental part of the paper we investigate the accuracy characteristics that reflect the ability of the video camera control system to react to the behavior of the observed dynamic object.
