Current states of mechatronic systems and the state of control objects in every cycle of functioning are usually evaluated with the aid of a set of values of controlled parameters, which are formed with measuring tracts of the system on the basis of signals of sensors. Presently, methods of the analysis of trends of changing the system parameters and control of their location within the limits of warning and emergency intervals are widely used in mechatronics. However, this provides identification of facts of development of already formed negative tendencies, when urgent managerial decisions and technical measures are required for avoidance of emergency situations. More effective control may be implemented during early assessment of the events, what is very important for mechatronic systems, in which systematic processes relatively quickly take place. In connection therewith the cyclic use has been considered of the three-stage process of continuous dynamic tracing of temporary rows of controlled parameters and the use of a fuzzy logic apparatus with the coded fuzzyfication for taking operative decisions about discovery of negative trends in each of five consecutive intervals of observation. Development of solutions in the mechatronic system about the steady increment or decrease of individual parametrical trends or availability of trend flats can be carried out with the aid of a finite set of production rules, which form a consecutive structure of logical conclusions. As for the logic of the simplest procedures of tracing the migration of parameters and production rules of generation of solutions are implemented in processors which support operations with a floating point and logical digit-to-digit operations.
