Abstract

The problem of implementing joint control actions on electromechanical devices (EMD) in human-machine systems through the control body of a human-machine interface is considered. Based on the theory of optimal control, control functions between the human operator, the program control automaton, and the corrective control automaton are synthesized. Peculiarities of the technical implementation of the control actions on the EMD of the ergatic system using the new type of joint control devices have been identified, through the control body of which information interaction between the human operator and the system automa-ton is carried out. Based on the model of actions and responses of the human operator and machine, which is adopted in engineering psychology, mathematical models of their joint control of the object have been developed. Mathematical models of machine responses are constructed using the hypothesis of complete certainty in the form of a normal system of ordinary differen-tial equations. As a result of combining action and response models for the human-machine system, a finite set of incomplete representations of the elementary motions of the image point in the state space is obtained, on which the programmed motion of the object is built in the form of a sequence of elementary motions. Virtual discrete control signals Corresponding to specific positions of the control bodies of the joint control apparatuses of the human-machine interface of the system are determined, through which consecutive transitions from one elementary movement to another are carried out. The conclusions on the effectiveness of the use of joint control in transport ergatic human-machine systems are formulated. It is shown that in this case, the advantages of control partners are used and combined to the greatest extent.

Highlights

The problem of the distribution of control functions between a human operator and a machine in an ergatic system does not lose its relevance when creating new automated systems [1, 2]
If we take into account that manual control in the ergatic human-machine system is carried out using the control unit of the human-machine interface of the system, it is relevant to study the possibilities of controlling the object of the ergatic system through this control unit, simultaneously from the side of the human operator and the control automaton of the system when combining control actions
The technical implementation of joint control of an object should correspond to such an algorithmization of the actions of a human operator and a control automaton, in which control according to the selected criterion would be optimal [3]

Summary

Introduction

The problem of the distribution of control functions between a human operator and a machine in an ergatic system does not lose its relevance when creating new automated systems [1, 2]. If we take into account that manual control in the ergatic human-machine system is carried out using the control unit of the human-machine interface of the system, it is relevant to study the possibilities of controlling the object of the ergatic system through this control unit, simultaneously from the side of the human operator and the control automaton of the system when combining control actions. There are no theoretical and experimental studies and models that fully support the use of combined control by “control partners” in the design of ergatic human-machine systems. In this regard, the task of studying the capabilities and features of the implementation of the combined control actions on the EMD in the human-machine systems through the control device of the human-machine interface is considered
