Abstract
The paper proposes to evaluate achievement of main results in operation of intellectual mechatronic systems with digital control by the obtained information effect. In this respect, common information requirements with intellectual components are considered as a basic information factor which influences on the process of mechatronic system designing. Therefore, some parameters have been accentuated and they can help to provide rather complete description of the processes used for obtaining and using systematic information within the volume of the intellectual mechatronic system. Conformity degree of control vector parameters synthesized by the system and identification results of its current states have been selected as an information criterion of the control efficiency. A set of expected probability values for location of each parameter of an control object and a mechatronic system within the required tolerances has been used for formation of possible states. The paper shows that when a complex information description of the system is used then it is expedient to use an expert assessment of selection probability for allowable control vectors which ensure a system transfer to favorable states. This approach has made it possible to pinpoint main information and technical specifications of the intellectual mechatronic system: structural construction (informational and technical compatibility and information matching of its components); control object (uncertainty of its state and information vector, information capacity of the mechatronic system); control actions (their hierarchy and entropic balance of control process, managerial resource of mechatronic system); functioning result (informational effect and control efficiency criterion, probabilistic selection of system states). In accordance with the fulfilled analysis it is possible to note the most effective directions for practical use of the proposed informational approach for creation of the intellectual mechatronic system: comparison of alternative design solutions based on the analysis of calculation assessments on unconditional entropy of the control object and the system; simulation with the aim to accept a final systematic option while constructing digital controlling block of the created system; complex application of experts’ knowledge, most comprehensive introduction of knowledge to the process of mechatronic system designing.
