包装机给料系统鲁棒控制器设计

Robust Controller Design for a Feeding System of Packaging Machine

阐明了包装机连续给料系统自动称重计量的基本原理 ,确定了系统各组成环节的数学模型 ,分析判断了系统的固有性能 ,并设计了一个较为理想的鲁棒控制器 。

The automatically weighting principle on a feeding system of packaging machine was reviewed. The mathematical model of the links in this system was established and the inherent performance of the system was analyzed. The relationship between H ∞ optimization and robustness was investigated, and a design method of robust controller was given. To improve the dynamic performance of the original system, an ideal robust controller was designed. The design concept of this robust controller is also available for the similar control system. The simulation results verify the correctness of the design idea.
