Loop-shaping characteristics on Hand position Control of a Human Operator in a Human-machine Control System

Abstract

This paper deals with loop-shaping characteristics on hand position control of a human operator in a human-machine control system. We consider that a human-machine control system generally can be regarded to comprise a hand position control subsystem which consists of mechanical dynamics of the operator and the machine. In this paper, we investigate this subsystem and properties of human operator on adapting his mechanical dynamics to the machine. As a result, loop-shaping characteristics of a human operator on his hand position control are discovered. The knowledge of the characteristics is quite useful for designing mechanical dynamics of the interface part of the human-machine control system.
