Fuzzy modelling in energetic

Application of fuzzy control in consumer electronics is a daily practice. In energetic there are also promising areas, especially in power industry, air conditioning and heating technology. We attempt to apply fuzzy control technique to small household boilers. A demonstration of this application is presented in this paper. The goal was to keep the outcome temperature of the domestic hot water at a given constant value; meanwhile the temperature of the incoming water was changed. We also examined the effects of the regular and random perturbation in the input mass flow. At last we pointed out some potential possibilities of this development in the increase of the energetic and environmental effectiveness. In the first step, the control algorithm is based on the well-known classic Mamdani approach, because in this system the number of variables is small. However, in further prospective systems we integrate several components and our intention is to use various complexity reduction approaches especially fuzzy rule interpolation techniques. At these complex systems the hierarchical interpolative fuzzy control are reasonable and applicable
