A Method of Decreasing the Amplitude of Hunting of Relay Servomechanism Operating on Sampled Data

Abstract

In the preceding papers, the method of analyzing the hunting or on-off control system operating on sampled signals were treated. In this paper, we will show how to decrease the amplitude of hunting and design a desired control system. A device of obtaining differentials will also be explained. Especially for the controller designed by the authors, the decrease of amplitude is analytically calculted and the result is compared with that of the experiment. Experiments were also carried out with continuous and sampling relay control systems, with and without hysteresis and the results were compared with each other.
