Abstract

The invention discloses a high-precision thrust servo controller, which solves the problems of high cost, complex structure, poor stability of the excitation power supply and servo control current, and cannot meet the requirements of high-precision thrust in the on-site thrust calibration system. Calibration usage requirements issue. The controller includes a precision DC power supply module, a standard force signal amplification module, a servo valve control module and a digital display meter; the precision DC power supply module is connected with a standard force sensor, a standard force signal amplification module, a servo valve control module and a digital display meter respectively, It is used to provide stable power supply to the standard force sensor, standard force signal amplification module, servo valve control module and digital display; the input terminal of the standard force signal amplification module is connected to the output signal of the standard force sensor, and the output terminal is connected to the input terminal of the servo valve control module Connection, the output end of the servo valve control module is connected with the external thrust loading servo valve. The digital display meter is used to visualize the circuit parameters, which is convenient for the operation and control of the calibration process.

Description

technical field [0001] The invention relates to a controller, in particular to a high-precision thrust servo controller. Background technique [0002] At present, in the large-range thrust automatic calibration system, the servo valve is generally used to control the hydraulic system to apply force to the standard force and the measuring force sensor. The output data is used as a standard, combined with the output data of the measuring force sensor, to complete the calibration of the thrust measurement measurement system. This working method is simple, reliable, and has high accuracy, and is widely used in engineering sites. [0003] In the thrust field in-situ automatic calibration system, the servo controller completes the excitation of the standard force sensor, and the servo hydraulic system receives the control of the servo controller to complete the thrust loading and state transformation. The performance of the servo controller is directly related to the accuracy of t...
