Displacement control signal correction method, displacement control device, construction machine and displacement control signal correction program |
摘要 |
The present invention includes: a displacement altering means 4 for generating a displacement control pressure P corresponding to a displacement control signal i; an input means 12 for inputting a target displacement theta; a pressure calculating means 10 for calculating a displacement control pressure P corresponding to the target displacement theta based upon predetermined reference characteristics of the displacement altering means 4 ; a pressure detecting means 5 for detecting a pressure Pa corresponding to the displacement control pressure P; a signal calculating means 10 for calculating a displacement control signal i corresponding to the input target displacement theta; and a correcting means 10 for correcting the displacement control signal calculated by the signal calculating means 10 based upon the displacement control pressure P having been calculated by the pressure calculating means 10 and the measured pressure Pa detected by the pressure detecting means 5.
