Industrial Automatic Control Systems and Controllers Annotation << Back The Synthesis of System of Detection of the Abnormal Condition of Objects in the Conditions of Insuffi cient Information to Form a Feature Space A.A. Dvilyansky, V.B. Ivkin, A.A. Selin One of the milestones in designing an automated process control system (APCS) is a study of issues, connected with fault-tolerance approach. The content of above-noted issues is to analyze the trouble causes of the normal equipment mode and an evaluation of probable time-response characteristics of events as a trigger for its occurrence. The above mentioned determines a system synthesis relevancy of diagnosing an abnormal industrial facility conditions in the phase of its beta testing aimed to conditional detection that antecedes the instant of failure. This report substantiates the synthesis strategy of a similar systems on basis of an incremental-decremental approach to behavior analysis of existing factors describing a component behavior of designed objects. Also proposed the dependences that characterize the behavior of diagnosed essential factor available from actual test. Substantiated fi ndings that defi ne the area of application of the considered systems and especially the reduction of feature spaces used at the initial stage of the operation systems. Keywords: automated process control system (APCS); a detection system of abnormal object state; an incremental-decremental approach; attribute spaces reduction.
