Targeting of Joint Control in the "Man-Machine" System: Modeling and Structuring

Abstract

The category of target designation is considered as the upper level of joint control of an object in the ergatic system "man-machine". Target designation refers to the initial need that precedes the planning and execution of the controlled movement of some object of the ergatic system. Such management is presented as a variant of situational management, defined by D. S. Pospelov on the basis of a model of actions and responses of a human operator and a machine adopted in engineering psychology. The control automaton of the system is given the properties inherent in the human operator. The anthropomorphism of control actions is used in the construction of the designation of the control automaton on a set of incomplete representations of elementary movements of the depicting point along the trajectory in the space of states of the "man-machine" system. It is shown that the angular points of the trajectory mark complete situations in the state space, the change of which is caused by signals of discrete anthropomorphic control. The change of situations and elementary movements are matched with the elementary goals and intermediate goals in a structured hierarchy of a complete system of target designation goals, arranged in time. Quantitative estimates of the complete system of goals were obtained. The principal possibility of structuring target designation at the entire stage of operation of the vital cycle of the "man-machine" system is shown. The description of the adopted approach to the design of target designation is accompanied by an example of the application of methods of the theory of optimal control and expert opinions and assessments of boatmasters for the organization of anthropomorphic control of the vessel’s movement in conditions of increased danger. The results of the analysis of experimental data are presented, according to which quantitative estimates of the complete systems of goals implemented in the executed movements of ships are given when the main goal is achieved — the entry of the vessel into the lock chamber. The analogous estimates for comparison are made according to the patterns of anthropomorphic management developed for the same main purpose. The results of the discussion of the results of the study are presented. The possibilities of taking into account the parametric, signal and coordinate uncertainties of mathematical models for the coordination of target designation with the planning of anthropomorphic ship movement control are shown.
