Modelling HP steam generator with FUZZY feedforward control systém
Result description
Currently, in the energy industry is given a lot of attention to the environment. In this area, there is an effort to increase efficiency and achieve smaller energy losses. One of the ways to achieve higher efficiency is to design a new control structure. Current feedback control system is designed with conventional PI controllers with variable parameters. This paper describes a possible method of substituting an optimally set feedback PI-controller for fuzzy feedforward control. The principle is basedon the direct relation between the value of power level and valve setting, which is applied through fuzzy logic. Testing and experiments proceed on a developed non-linear simulation model. The paper presents different variants of generating influencing values for the various deffuzification methods or a different selected power sequences. The resulting output temperatures are compared with obtained feedback control curves.
