Abstract

The invention provides an inductosyn angle automatic detection device and method and belongs to the detection technical field. According to the device and method, after the calibration of the angle measurement value of a turntable is completed, a starting angle and the number of sampling points are inputted; a test computer controls the turntable to move to a measured angle, and automatically completes the collection and storage of measurement data; after completing the data collection, the test computer can perform online angular position error calculation, model coefficient identification and error compensation according to measured data, thereby realizing the automatic detection of the angle. With the device and method of the invention adopted, problems such as undesirable compensationeffect, limited sampling points, difficulty in model establishment, large data storage amount, much human participation and low work efficiency of an existing inductosyn detection and compensation method can be solved.

Description

technical field [0001] The invention relates to an automatic detection device and method for an inductive synchronizer angle, belonging to the technical field of detection. Background technique [0002] The paper "Adjustment and Compensation of Inductive Synchronizer Angle Measuring System Error" (Journal of Harbin Institute of Technology, Zeng Qingshuang, 199802) analyzed the operation that caused the first harmonic and second harmonic errors of the inductive synchronizer angle measuring system, and proposed the first harmonic Compensate and adjust the method of the second harmonic, and design the compensation circuit of the first harmonic error. The two errors are adjusted and compensated by the measured data, which improves the angle measurement accuracy of the induction synchronizer. Its disadvantages are: it mainly adopts the method of hardware compensation, and only for the short-period first harmonic error and second harmonic error, which has relatively large limitat...
