Abstract
The processes of mobile objects control are deploying in space and time on the basis of current scientific concepts. They are inseparably connected with the processes of transformation of matter, energy and information. Therefore the feasibility of using the information theory mathematical apparatus to analyze of management processes in general, and the mobile objects radio control processes become clear. The static approach to this problem is based on determining The amount of information that must be entered in the control loop to reduce the entropy of the control object from a starting value to a final value. The entropy determines the accuracy of the control. The dynamic control process remains hidden. It does not enable to establish the necessary control time, the laws entropy reduce and the relationship between the main indicators of the control process. Radio control systems have one thing: the entropy of the control object and control process is reduced because the control supplied information. Entropy is the objective characteristic of control precision. The information consists of the initial information and the operation information. The initial information is a set of pre-collected data about the properties of the control object, the disturbance and other factors. Working information is extracted in the control process. It is necessary to create the control process dynamic model which reveals the patterns of change in the control object entropy both in the absence and presence of control information. It should be appreciated that as the law of entropy reduction and the amount of control information depend on the organization of control process and the nature of information exchange between the control part and the control object. The radio control system decomposition is made. The іformation communications between the object and the control section are considered. The time needed to reduce the entropy to the prescribed value is set. The situation that occurs in conditions of increasing entropy unmanaged object is analyzed. Conditions entropy reduction in the event of control information and necessary control time are mounted. A situation with known radio control system potential is analyzed. The loss of information impact in the control object on the change in entropy pattern is considered. The needed control time in a loss of information is established. The possibility of implementing the control process in a loss of information is defined. Conclusion. The entropy analysis based on the proposed dynamic models of radio control process is executed. The relationship between the entropy of the control object and the speed of control information entry is installed. The necessary control time to reduce the entropy is determined. The radio control systems potential possibilities are taken into account. The impact of information loss in control object to reduce the entropy is studied. The effect of feedback between the control object and control part on the process dynamics is established. These results provide a new level of radio control process analysis of moving objects.
