PREDICTIVE ADAPTIVE FEEDFORWARD CONTROL OF A TIME SCALED SOLAR PLANT

Abstract This paper concerns the control of a solar energy collector field using predictive feedforward adaptive control techniques based on multiple identifiers. The ACUREX field used in these work is described by a partial differential equation (PDE). The plant is characterized by: non linearity, fast accessible disturbances and time varying dynamics. The dynamic dependency on flow is overcome by time-scaling. The result of this transformation is a discrete linear model with a Finite Impulse Response (FIR) transfer function. This means that the optimal predictive controller is given by a feedforward block. Simulation results on a detailed plant physical model are presented in order to illustrate the method.
