Abstract

This paper shows the application of robust control techniques to asolar plant integrated in an air conditioning system. Differentstructures in an specific loop are applied, because of thecomplexity of the whole system. Besides the classical feedbackloop, the plant controller includes also a feed forward one toreject measurable disturbances as radiation. The designmethodology and some simulations examples will be exposed.Finally, several experiments to test the validity of thecontrollers are performed in the real plant.
