The water flow rate control, which is the principal control loop required to operate stationary solar fields, can be as simple as designing a PID controller for a unique pump whose behavior can be approximated by a first-order system with delay. Nevertheless, when the water flow rate is manipulated with multiple actuators (pumps or valves), the problem presents some challenges due to hydraulic interactions. This paper presents a multivariable controller scheme to deal with the control of a solar field with five pumping systems. Simulation and experimental results are included to demonstrate the effectiveness of the proposed controller.

Abstract

The water flow rate control, which is the principal control loop required to operate stationary solar fields, can be as simple as designing a PID controller for a unique pump whose behavior can be approximated by a first-order system with delay. Nevertheless, when the water flow rate is manipulated with multiple actuators (pumps or valves), the problem presents some challenges due to hydraulic interactions. This paper presents a multivariable controller scheme to deal with the control of a solar field with five pumping systems. Simulation and experimental results are included to demonstrate the effectiveness of the proposed controller.
