The control method trough collector of the polar axis tracking structure

A method of controlling trough collector structure-based polar axis tracking of solar thermal applications belonging to the field, which is characterized in that it is a control method of the structure: (1) setting an initial value; (2) Calculate n, δ ; (3) calculating ωsr, ωss, tss, tsr, ΔB; (4) calculating tz, tz≥tsr, is executed (5), otherwise, return (4); (5) overcast, is returned (5 ), otherwise, performing (6); (6) touch the limit switch, that the structure is stopped, otherwise, the process (7); (7) [gamma] s is calculated, the adjustment αs, γs, performing (8); (8) Comparative R2, R'2, R "2, R" '2, R2 = R2' = R2 "= R2" ', is maintained αs, γs, performing (13), otherwise, the process (9); (9) R2 ≠ R2 '≠ R2 "≠ R2"', is sequentially adjusted αs, γs, performing (13), otherwise, performing (10); (10) R2 = R2 '≠ R2 "= R2"', is adjusted aS performing (13), otherwise, performing (11); (11) R2 = R2 "≠ R2 '= R2"', is combined S adjustment [gamma] s, execution (13), otherwise, performing (12); (12) Looking Rmin of, successively adjust αs, γs, performing (13); (13) Δt ended is performed (14), otherwise return (13); (14) tz≥tss, that the structure is stopped; NO, execution ( 5).
