Abstract
PURPOSE: To determine the control level of a flow control valve with a control parameter value calculated from the flow rate and loss resistance of the value.
CONSTITUTION: The opening rvp of a flow control valve is detected with an opening detector 8 to calculate a loss resistance rvo with respect to the opening rvp rate g0 detected with a detector 4 are inputted into a parameter computing section 7 to calculate a time constant T and a gain K, based on which a proportional gain K and an integral time Ti are computed. Both value K and Ti determine a control level P at a flow rate control section 5 to control the flow control valve 6. The proportional gain K and the integral time Ti can be regulated to an optimal value according to the flow rate and the loss resistance thereby always ensuring a better control.
