摘要
该文通过分析近零点阶跃误差与整尺和余尺的关系,从而提出了基于整尺和余尺的两种相位校正方法来消除误差和接近零点误差之间的关系。在Matlab平台上,在距离正向和反向变化、距离慢变和快变等情况下对这两种方法进行了仿真测试。仿真结果表明,可以在距离缓变的情况下使用整尺的相位校正方法完全消除近零点的阶跃误差;基于余尺的相位校正方法不但具有整尺的相位校正方法的校正能力,还可在距离快变的情况下完全消除近零点的阶跃误差。
This paper analyzes the relationship between near zero step error over the entire foot and the foot,which made the relationship between error and error close to zero based on the entire foot and two feet over phase correction method to eliminate.On Matlab platform,in forward and reverse changes in distance from the slow change and change fast and so the simulation test of these two methods.Simulation results show that can be used in the case of the whole foot distance graded phase error correction method to completely eliminate the step of nearly zero;based on more than foot phase correction method not only has the ability to full scale calibration phase correction method,but also in when the distance quickly become completely eliminate the step of nearly zero error.
