基于状态观测器的软测量在管道煤气控制系统中的应用研究

The Application of soft measurement based on state observer in pipe gas control system

状态观测器作为对系统中不可测量状态进行估计或重构的方法,有着非常完善的理论研究体系。在管道煤气控制系统中,将状态观测器作为软测量的一种设计方法,不但可为软测量的参数估计提供一种良好的系统结构,而且可以充分保证参数估计过程所需要的稳定性和良好的收敛速度等性能指标。

The state observer is a very important tool to reconstruct or estimate the system states which can not be directly measurable. Used as soft measurement in pipe gas control system, the observer has a perfect system structure, and all the performances, stability, the fast velocity of the convergence ,etc, can be ensured for the parameters estimation process.
