Introduction. The basis of modern information technology for complex automation systems in the face of uncertainty is the principle of situational management. Such technologies include the following: expert systems, neural network structures, fuzzy logic and associative memory. The development of intelligent technologies is associated with the combination of various methods of processing knowledge. This area provides increased performance, reduced knowledge. It is supposed that fuzzy logic and expert systems can be combined. Aim. Consider the task of improving recognition algorithms in control systems by combining optimal filtering methods and fuzzy logic at the stage of secondary processing of information about object parameters. Materials and methods. For preliminary processing, we will consider Kalman filters (FC), for the implementation of which in real time less computing resources are required in comparison with guaranteed estimation algorithms. In the proposed method, we apply FC Bank. We carry out mathematical modeling in the Mathcad 14. In the FuzzyTECH software environment, a fuzzy project “Recognizing the type of an object” is being developed. Development of a fuzzy model takes place in several stages. Firstly, the presentation of input variables in terms of linguistic variables. Secondly, relying on expert knowledge, we define terms for linguistic variables. Thirdly, the creation of a block of rules. Fourth, a study of the created fuzzy project. Results. The mathematical modeling of the FC in the devices for tracking the parameters of objects in the process of recognition in the Mathcad 14 software environment showed the possibility of using a filter bank in the considered devices. Algorithms for recognizing object types using fuzzy logic have been created and studied. Conclusion. The created control system algorithms, combining Kalman filtering and fuzzy logic, increase the efficiency of the recognition system.
