Characteristics of Human Operator in Manual Tracking Control System

Identification of operator handling characteristics has got the great attention of many people, especially for the intelligence of the machine. This article designs a manual tracking control experiment to analyze the human operator control characteristics. The whole experiment system is composed by a computer and a joystick. The computer simulate the target ball's movement, human operator can control the reference ball by the joystick to track the target ball. By changing the target ball's speed to identify the human operator control effect. According to record and analyze the deviation of the experiment data, achieved some tracking control characteristics of the operator: first, every operator has a time delay between he discovers the target and operates the machine to track it, this time is about 0.4s, second, the operator's tracking performance is related to his operating skill, in addition, tracking effect depends on the target's speed, the more difficult of the experiment task is, the poorer of the tracking effect is.
