Abstract

The invention discloses an electrohydraulic position servo controller which comprises a comparator, a first potentiometer, a first integrator, a first subtracter, a second subtracter, a second potentiometer, a second integrator, a third subtracter, a fourth subtracter, a third potentiometer and a third integrator connected in series. The output end of a follower is connected to the input ends of the comparator, a fourth potentiometer and a first differentiator. The output end of the fourth potentiometer is connected to the input end of the first subtracter in series. The output end of the first differentiator is connected to the input ends of the second subtracter, a fifth potentiometer, and a second differentiator. The output end of the fifth potentiometer is connected to the input end of the third subtracter in series. The output end of the second differentiator is connected to the input end of the fourth subtracter in series. The electrohydraulic position servo controller has the advantages of complete functions, simple interfaces, the full feedback of displacement, velocity, acceleration and other state variables can be realized, a controlled electrohydraulic servo object has fast response without overshoot and has strong load disturbance resistance ability.

Description

technical field [0001] The invention relates to an electro-hydraulic position servo controller, more specifically, to an electro-hydraulic position servo controller which adopts an analog circuit and has extremely strong resistance to load disturbance. Background technique [0002] As we all know, the precise control of the electro-hydraulic position must adopt the closed-loop feedback control method to obtain better control accuracy. The traditional electro-hydraulic position servo controller is proportional to the error signal between the input and output in its forward channel (P control), proportional plus integral (PI control), proportional plus integral plus differential (PID control) operations to generate displacement control signals, thereby providing precise adjustment for the position of the electro-hydraulic servo object. [0003] The above-mentioned control methods can be classified as PID control, and its effect on the position control of the electro-hydraulic ...
