动态测量是被测参数处于动态情况下的测量 ,这时系统的内部状态、结构和动态特性在受到干扰时随时间变化而变化 ,将产生测量误差。由于这种动特性 ,动态测量误差是未知的 ,为了得到较高的测量准确度采用实时误差修正技术是一种较好的途径。本文采用灰色模型进行预测修正得到很 Dynamic measurement is measured under the dynamic conditions of the measured parameters, then the system’s internal state, structure and dynamic characteristics of the interference changes with time changes will result in measurement error. Because of this kind of dynamic characteristic, the dynamic measurement error is unknown, in order to obtain the high measurement accuracy, the real-time error correction technique is a better way. In this paper, the gray model is used to predict and correct
