Dynamic Weighing of the Application Based on Parameters Identification

In the process of agricultural livestock of feeding, it is increasing for feed of livestock of online dynamic weighing measurement demand, But the dynamic weighing is the more important and complex than the static weighing, and it is very difficulty to achieve the technology. Researching a high precision and high speed dynamic weighing algorithm is great value to improve equipment of productivity and efficiency. This article is about the general dynamic weighing system equivalenting to the general second-order control system. There derives the static and dynamic mathematical model through control theory. And it converses into the Autoregressive Moving Average Model by Laplace Transform,then it converses into Least Squares parameter identification problem.Finally,there analysises Least Squares parameter identification in the weighing process of application.
