Abstract

PURPOSE: To compensate the response delay due to the time which is required for discharging the capacity of the integral time constant, by detecting both when the setting input has been varied and when the feedback input has approached the value of the setting input, and shorting the capacity of the integral time constant in the control device.
CONSTITUTION: When a variable signal has been inputted to the speed setting input A, an input signal C of the addition amplifier 4 is varied in proportion to the difference between the input A and the speed feedback input B. An output signal D of the amplifier 4 is compared with the threshold value, and when the value of the signal D has exceeded that of the threshold value H, transient is caused in the output E of of the amplifier 5. Transient in the positive direction is inputted to a differentiator 9, transient in the negative direction is inputted to a differentiator 10 through the inversion amplifier 8, and a pulse in the positive direction is outputted to the outputs F and G. These signals are inputted the base of the transistor 12, short a capacitor of the time constant circuit by driving a relay Ry, and its electric charge is discharged in a short time. In this regard, the same action is caused, as well, when the input B has approached the input A, and the signal D has exceeded the threshold value in the backward direction.
