Output Temperature Control of a Flat Plate Solar Collector Subject to Time-Varying Environmental Conditions

Resumen: Solar collectors are heat exchangers that transfer solar energy to a fluid in the form of heat; however, the problem is that solar energy is not constant, and it is essential for industrial applications the deliver a continuous thermal load or constant temperature. In this paper, we avail of a nonlinear mathematical model developed by us. Such a model predicts the collector's output temperature subject to time-varying, unknown solar irradiance, ambient temperature, and wind speed. To deliver a constant temperature at the collector outlet, we designed a PI control, considering the derivative of the input flow (dṁ/dt) to the collector as a manipulated variable. We show its applicability through simulation but considering natural environmental conditions.
