Abstract

PURPOSE: To perform bumpless conversion on the selection of controlling purpose by following analog memory for doing bumpless automatic-manual conversion of a proportional integrator to the control outputs when the controlling purpose is not selected.
CONSTITUTION: In case of controlling pump discharge pressure or discharge flow gain by changing velocity of a pump 8, outputs of a pressure signal generator 11 and a flow signal generator 12 are transmitted to controllers 1, 2, which are exercised proportional integrating operation, and given out the outputs as a settled value of an automatic velocity controller 5 of a motor 6. In case of making discharge pressure controls, 103, 104, 204 are functioned as automatic mode, 203 as manual mode, 107 is converted on the side of A1. Then, control outputs are given out through a signal converter 4 when they are transmitted to an analog memory 204, a proportinal integrator 203, those outputs are followed to the control outputs. In consequence, even through they are converted to the flow gain control, bump is not produced.
