Abstract

The invention discloses a realization circuit of adaptive compensation of a sensor dynamic response. To be specific, the invention relates to the instrument, electronic measurement and automatic controlling fields, particularly to a hardware realization method of the adaptive compensation of sensor dynamic response. The provided circuit is mainly used for solving technical problems of time delay, noise interference, complex data processing and the like due to utilization of the dynamic compensator. With the dynamic compensation circuit, utilization of a complex software processing algorithm and a high-end DSP processing chip can be avoided; the data process complex response speed is fast; and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of sensor dynamic response, in particular to a circuit for realizing adaptive compensation of sensor dynamic response. Background technique [0002] The dynamic response characteristics of sensors will directly affect the test performance of the back-end test system, especially the dynamic response characteristics with oscillation characteristics will affect the test accuracy and test speed. For example: the output response of the load cell is not only affected by the weight of the sensor itself, but also by the weight of the object to be measured. The load cell is composed of a strain gauge and an elastic body. Because the damping ratio of the elastic body is too small, the sensor takes a long time to reach a steady state, and the dynamic characteristics are poor, so it is difficult to meet the requirements of rapid measurement. Improving the rapidity of the dynamic response of the sensor can start from tw...
