Parallel tiered and dynamic models of the fuzzy inference in expert-diagnostic software systems are considered, which knowledge bases are based on fuzzy rules. Tiered parallel and dynamic fuzzy inference procedures are developed that allow speed up of computations in the software system for evaluating the quality of scientific papers. Evaluations of the effectiveness of parallel tiered and dynamic schemes of computations are constructed with complex dependency graph between blocks of fuzzy Takagi – Sugeno rules. Comparative characteristic of the efficacy of parallel-stacked and dynamic models is carried out.

Abstract This article outlines a methodology of modeling self-induced vibrations that occur in the course of machining of metal objects, i.e. when shaping casting patterns on CNC machining centers. The modeling process presented here is based on an algorithm that makes use of local model fuzzy-neural networks. The algorithm falls back on the advantages of fuzzy systems with Takagi-Sugeno-Kanga (TSK) consequences and neural networks with auxiliary modules that help optimize and shorten the time needed to identify the best possible network structure. The modeling of self-induced vibrations allows analyzing how the vibrations come into being. This in turn makes it possible to develop effective ways of eliminating these vibrations and, ultimately, designing a practical control system that would dispose of the vibrations altogether.

En la presente memoria se propone un m´etodo para sintonizar una ley de control difusa proporcional retardada (PR) para estabilizar una clase de sistemas no lineales. La estabilidad del sistema no lineal se garantiza mediante la σ−estabilidad de su modelo difusos del tipo Takagi-Sugeno (T-S) en lazo cerrado con una ley de control difusa PR. La sintonizaci´on de la ley de control difusa PR se realiza en el marco frecuencial empleando el m´etodo Dparticiones. Sin perdida de generalidad, los resultados te´oricos obtenidos son ilustrados en un sistema carro-p´endulo. El desempe˜no del control propuesto aqu´ı es comparado con una cl´asica compensaci´on paralela distribuida.
