En Irish Signals and Systems Conference (ISSC) Maynooth, Ireland: Institute of Electrical and Electronics Engineers (IEEE).978-1-7281-2800-9https://hdl.handle.net/11441/109029The estimation of unobservable states of a process is important when using control techniques that assume, said a priori, known values. The controllers based on the state space present good behavior and efficiency, even when the dynamics of the process are non-linear. One of the processes with non-linear dynamics and in which not all the states are observable is the case of parabolic trough solar plants. In this work an observer is presented, based on a fuzzy inference system, for the estimation of the temperature profiles of the loops that make up the solar field.
