FUZZY MODEL BASED CONTROL OF DYNAMIC SYSTEM

Abstract

The paper deals with the relatively universal method of ivestigation and fuzzy description of the basic qualitative characteristics of dynamic systems. A relatively simple universal fuzzy model of a dynamic system has a firmly defined dynamic section of dynamic system, covers the whole operational area of the dynamic system and does not require a complicated procedure for determining the rules of the static fuzzy section of the fuzzy system model. This approximation can then be used as the basis for the design of simple robust regulation structures suitable for systems characterized by imprecisely defined parameters and possibly also structure. The intention of the control algorithm introduced was to enable control a dynamic system with a little previous knowledge as possible and to avoid the heuristic search for a rule-based fuzzy controller
