Abstract-This paper deals with the control of concentrating parabolic solar collectors by forcing the outlet oil temperature to track a set reference. A fuzzy universal approximate model is introduced in order to accurately reproduce the behavior of the system dynamics. The proposed model is a low order state space representation derived from the partial differential equation describing the oil temperature evolution using fuzzy transform theory. The resulting set of ordinary differential equations simplifies the system analysis and the control law design and is suitable for real time control implementation. Simulation results show good performance of the proposed model.

“…En [6], los autores proponen un modelo adaptativo MPC en el espacio de estados para el control del campo solar con una estimación mediante Unscented Kalman Filter (UKF). Un MPC más avanzado en el espacio de estados se presenta en [7] donde se propone un observador de Luenberguer para la estimación de los estados. Un Extended Kalman Filter (EKF) se propone en [12] para la estimación de las temperaturas de internas del lazo y de entrada suponiendo que no existe un sensor a la entrada y su aplicación en un PID.…”

ResumenLa estimación de los estados no observables de un proceso es importante cuando se usan técnicas de control que suponen dichos valores conocidos apriori. Los controladores basados en el espacio de estados presentan un buen comportamiento y eficiencia, aún cuando la dinámica del proceso es no lineal. Uno de los procesos con una dinamica no lineal y en la que no todos los estados son observables es el caso de las plantas solares cilindroparabólicas. En este trabajo se presenta un observador, basado en un sistema de inferencia borroso, para la estimación de los perfiles de temperatura de los lazos que componen el campo solar.Palabras clave: Estimador borroso; Planta cilindro-parabólica; Control basado en modelo En este trabajo trata sobre la estimación de los estados del campo solar basado en Fuzzy Logic.Actas de las XXXIX Jornadas de Automática, Badajoz, 5-7 de Septiembre de 2018 908

“…Augmenting the sampling time would produce slower reactions by the control algorithm and it is not desirable. Diminishing the sampling time may produce faster reactions of the controller but the high dynamics modes of the solar field may be excited as shown in [16]. Furthermore, the sampling time cannot be smaller than 10 s due to communication requirements of the data acquisition system.…”

Incremental State-Space Model Predictive Control of a Fresnel Solar Collector Field

et al. 2018

Model predictive control has been demonstrated to be one of the most efficient control techniques for solar power systems. An incremental offset-free state-space Model Predictive Controller (MPC) is developed for the Fresnel collector field located at the solar cooling plant installed on the roof of the Engineering School of Sevilla. A robust Luenberger observer is used for estimating the states of the plant which cannot be measured. The proposed strategy is tested on a nonlinear distributed parameter model of the Fresnel collector field. Its performance is compared to that obtained with a gain-scheduling generalized predictive controller. A real test carried out at the real plant is presented, showing that the proposed strategy achieves a very good performance.
