Abstract

Time delay by image processing exists in the information acquired from a CCD camera. Since renewal time of image information is longer than sampling time of control, control delay occurs and lowers the performance of feedback control. In this paper, in order to compensate image information delay, we propose the method that combined Kalman filter, time delay compensation, and state estimation between the sample points of image information. Advantages of the proposed method are demonstrated by simulation and experiments for the three-link space robot.
