About Realizations of Compatible Control Impacts on the Object in the Man—Machine Systems

Abstract

We consider the problems of implementing control actions on the object in the ergatic system man—machine, combined through the control body of the human-machine interface apparatus, in order to effectively distribute the control functions between the human operator and the system’s control automat. Peculiarities of technical realization of operating influences on object ergatic system using the apparatus combines new type of control, through a management body of which is communication between a human operator and automatic system. The principle of construction of joint control devices is shown with the help of pictorial models of discrete and continuous operation devices that have an Electromechanical drive device that reacts to signals from the control machine due to the movement of the control body. The devices provide for the possibility of moving the control body and the muscular effort of the human operator. For the verbal model of actions and responses of the human operator and the machine, adopted in engineering psychology, mathematical models of joint control of the object of the ergatic system, describing the movements of the control body, are developed. The mathematical model of the response of the controlled object of the system is represented by a normal system of ordinary differential equations. As a result of composition of models of actions and reactions for the system man—machine obtained a finite set of incomplete representations of the elementary movements depicting point in the state space, which is constructed for controlled movement of an object in a sequence of elementary movements. Virtual discrete control signals corresponding to specific positions of the control bodies of the joint control devices of the human-machine interface of the system, which are used for sequential transitions from one elementary movement to another, are determined. The results of approbation of joint traffic control of vessels using a mathematical model of actions and responses in full-scale experiments with increased requirements for safety and accuracy of movement are presented. Conclusions are formulated about the effectiveness of the use of Sov-local management in transport ergatic systems man—machine. It is shown that in this case, the advantages of management partners are most used and combined.
