Hybrid Fuzzy-PID Control in a Thermo Solar Power Plant Condenser

Abstract

In this paper a predictive hybrid fuzzy-PID control system is designed to be applied in a thermo solar power plant. The intelligent control system keeps the level of the condenser at a desired value. The condenser is a complex element in the plant and the uncertainty that comes from the weather conditions at its inputs makes the control difficult. The dynamic of the system changes continually, depending on the solar resource. The intelligent fuzzy system combined with a conventional one shows good performance, proving that the synergy of these techniques improves the control action
