Automation Elements of Mental Activity and Actions of Human Operator in Ergatic System “Man-Machine”

Abstract

The article demonstrates that the optimal distribution of control functions within an ergatic system “man-machine” is facilitated by the application of joint control over a system object on the part of a human operator and the technical means of control automation. It is suggested combining control actions on the object in time through a control body of a command device in the system “man-machine” interface. On the basis of the results, obtained in the engineering psychology field at studying the manifestations of a human operator mental activity in the actions, the authors made mathematical models of control actions influencing the object. The models included the motion coordinates of command device control bodies of a “man-machine” system interface. These models are used at the identification and mathematical description of object elementary motions in the form of incomplete representations as ordinary differential equations. The article provides a description for a set of incomplete representations of the object elementary motions. A set of representations built in such a way provides the basis for object automated joint control. Automation is based on the solution of a problem on making a sequence of the incomplete representations of elementary motions with a reasonable use of artificial intelligence and the problem of optimizing time points when such elementary motions change with the use of numerical methods. A practical part of the conducted research is implemented in live experiments with the vessels at the implementation of a controlled vessel motion from a pool into a lock chamber. Joint control application for a “man-machine” system provides opportunities in terms of the mutual education of a human operator and system automated device at the stage of operation in the ergatic system life cycle.
