CIRCUIT FOR CONTROLLING THE MOVEMENT OF FLUID-PRESSURE SERVO VALVE |
摘要 |
The control circuit of the invention includes a rectangular wave oscillator section, a detect-amplifier section for detecting the position of a spool moving in association with the flow of the hydraulic servo valve, and a comparator section for comparing the output of the detect-amplifier with the command signal for controlling the servo valve. The displacement of the spool of the linear variable differential transformer (LVDT) is compared with the signal voltage of a set value to control and keep steady the flow of the valve.
