摘要
Disclosed is a control system and a control method for controlling input power to hydraulic pumps of hydraulic system including a prime mover (14) and a plurality of variable displacement hydraulic pumps (1, 1'; 1, 1', 1'') driven by said prime mover. The control system comprises: first computing unit for computing, for each of the hydraulic pumps (1, 1'; 1, 1', 1''), an input torque control value ( delta , delta '; delta , delta ', delta '') concerning a distribution of input torques of said hydraulic pumps from a representative pressure (P, P'; Ps, Ps'; Ps, Ps', Ps'') obtained on the basis of a discharge pressure (P, P'; P, P', P'') of at least one other hydraulic pumps; second computing unit for determining an input torque (T, T'; T, T', T'') for each of the hydraulic pumps on the basis of a corresponding one of the input torque control values determined by the first computing unit; and third computing unit for determining an object discharge rate (Qps, Qps'; Qps, Qps', Qps'') of each of the hydraulic pumps from the input torque obtained by the second computing unit and an own discharge pressure (P, P'; P, P', P'') of each of the hydraulic pumps.
