Title: Control circuit for fluid rate control valve
Inventor: ANDO TAKESHI
IPC: G05B11/36
Filed: 1993-07-20
Abstract: PURPOSE:To reduce the deviation between the fluid rate to be controlled and the set value and to control a fluid with high accuracy and with the reduced overshoot by providing a characteristic converting part in a closed loop control circuit and then using jointly the closed loop control and the open loop control when the preceding deviation is equal to a fixed value. CONSTITUTION:When a set input signal is supplied to a control circuit, a characteristic converting part 2 converts the input signal into a signal that changes the non-linear characteristic of a proportional solenoid valve 52 into the linear characteristic and outputs this converted signal. Thus an input voltage/control pressure characteristic curve becomes almost straight when the open loop control is applied to the valve 52. Meanwhile a feedback circuit amplifies the deviation between the feedback signal supplied from a pressure sensor 53 and the set value supplied from an input port 1 based on the gain set previously at a gain switching part 5. Then the feedback circuit adds the amplified signal to the output of the part 2 and supplies this addition signal to the value 52. In such a constitution, both the closed loop control and the open loop control are used together. Thus the fluid rate is controlled with high accuracy.
