Electro-optical Tracking Of Digital Acceleration Sensor System

In recent years, with the goal of the speed range tested to enhance and increase the degree of automation equipment for electro-optical tracking system to track and capture fast-moving target's ability to increasingly high demand. Target velocity will produce a large increase in angular velocity, angular acceleration as well as a greater angle Jerk, resulting in electro-optical tracking system dynamic error of a sharp increase in the target escapes field, tracking failure.The Title comes from Jilin Province scientific and technological development projects, "optical jitter suppression of adaptive filtering and feedforward control technology." Major research paper, the content of the composition of electro-optical tracking system, the principle of accelerometer and its electro-optical tracking system application. This study aims to target the original electro-optical tracking system to track the maximum angular velocity and maximum angular acceleration on the basis of ability to raise to the maximum angular velocity, maximum angular acceleration, and the introduction of accelerometer feedforward control system will be electro-optical tracking system, tracking error reduced to a minimum.This paper describes the electro-optical tracking system, the various components, as well as at home and abroad to improve electro-optical tracking system, some control methods, due to restrictions on the level of computer-controlled by changing the software control algorithms and a series of measures to track the effects of electro-optical tracking system, to change the situation is not very satisfactory. In the electro-optical tracking system, the introduction of accelerometers, through the acceleration of accelerometer output signal and the output of optical encoder position signal after two differential to be more accurate than the acceleration of the signal, using them to carry out feed-forward control can effectively improve the system tracking precision. This paper introduces the working principle of accelerometer and classification, this paper is CJ41A-2E-type piezoelectric Angular Accelerometer. Accelerometer during the installation process will produce error, c. paper gives the accelerometer during the installation process of the error compensation model.Finally obtained by Simulink simulation results show that using accelerometers after the feedforward control can effectively improve the tracking accuracy of optical tracking system, inhibit the system's jitter. Actual proof of the correctness of theoretical analysis in this paper and engineering application value.
