Abstract:
A control system for a hybrid construction machine includes: a turning motor provided in a turning circuit; a pressure detector for detecting a turning pressure of the turning motor; a variable displacement type of fluid pressure motor for regeneration which is rotated by means of pressurized fluid guided from the turning motor; a motor generator adapted to be rotated integrally with the fluid pressure motor; and a controller adapted to predict a turning regeneration flow from the turning motor on the basis of the turning pressure detected by pressure detector to control a tilt angle of the fluid pressure motor on the basis of the predicted turning regeneration flow.
