文摘

In this paper, a linear active disturbance rejection controller is proposed for a solar heating system assisted by ground-source heat pump, whose model is obtained by applying the system identification technique. The disturbances imposed on the heating system are estimated through an extended linear state observer and then compensated by a linear feedback control strategy. The proposed control strategy is applied to a 300 kW heating system to handle the thermal load variations of grid and process disturbances. The effectiveness of this controller is verified via a simulation study, and the results demonstrate that the proposed strategy can provide good tracking performance and disturbance rejection.
