In　this　work,　a　static　feedforward　strategy　for　concentrating　solar　energy　harvesting　is　proposed　to　confront　the　weather　and　load　fluctuations.　In　order　to　counteract　the　disturbance　and　maintain　the　outlet　temperature　by　regulating　the　mass　flow　rate,　we　derived　and　deployed　a　generalized　disturbance-control　equation,　which　could　precisely　describe　the　relationship　of　the　disturbance-manipulated-controlled　variables.　Based　on　this　equation,　disturbance-rejection　and　setpoint-tracking　tuning　issues　are　individually　studied.　Besides,　the　rationality　of　this　proposed　almost-linear　feedforward　scheme　has　been　numerically　assured　regardless　of　whether　phase-change　occurs.　Finally,　the　result　temperature　deviation　ranging　between　−2　°C　and　2.5　°C　is　still　tolerable　in　spite　of　harsh　operating　conditions　with　big　share　of　thermal　loss　(6%　relative　to　effectively-received　radiation),　poor　optical　efficiency　(50%)　and　steep　change　ratio　of　effectively-received　radiation　(±20%).　Compared　with　the　widely-adopted　PID　feedback　control　scheme　in　numerical　simulation,　the　feedforward　scheme　demonstrates　the　feasibility　and　superiority　in　targeted　regulation.　The　feedforward　strategy　directly　determines　the　manipulated　mass　flow　rate　to　answer　the　imposed　disturbance,　whereas　the　optimized　PID　scheme　costs　respectively　about　896　s　~　1504　s　and　658　s　~　1174　s　for　the　current　disturbance-rejection　and　setpoint-tracking　tuners.　Moreover,　the　controlled　outlet　temperature　costs　about　additional　200　s　on　the　basis　to　approach　to　the　setpoint,　of　which　the　delays　are　at　least　two　times　of　the　feedforward　scheme.　A　detailed　feedforward　measurement-control　program　has　also　been　presented.　Notably,　the　present　methodology　is　conducive　to　identifying　the　principal　portion　of　regulation　output,　which　is　of　particular　value　to　further　construct　high-performance　control　schemes.　©　2020　Elsevier　Ltd
