CONTROL SYSTEM FOR HYBRID CONSTRUCTION MACHINE

摘要

This control system for a hybrid construction machine is equipped with: a swing motor that is provided on a turning circuit; a pressure detector for detecting a turning pressure of the swing motor; a variable-capacity type fluid pressure motor for regeneration that rotates with a pressurized fluid introduced from the swing motor; a motor-generator that rotates integrally with the fluid pressure motor; and a controller that predicts a turning-regenerated flow quantity from the swing motor on the basis of a turning pressure detected by the pressure detector and controls the tilt angle of the fluid pressure motor on the basis of the predicted turning-regenerated flow quantity.
