Title :
A study on a full-electric control system of a hydro static transmission for construction machines
Author_Institution :
Yokohama Nat. Univ., Japan
Abstract :
A full-electric control system of a hydro static transmission for construction machines was studied. A simulation model was built. Dynamics of a pump swash plate were verified by experiment. Two-degree-of-freedom control was applied to motor speed control in order to improve responsibility, which was not enough in the case of feedback control because of oil compressibility in hoses.
