摘要
介绍了基于LQG基准的子空间辨识方法,可用于焦化生产过程控制中各类单回路控制器的性能评价。通过仿真实例验证了该方法的有效性,同时给出了输入方差不变时控制器理论上的提升空间。
This paper introduces a subspace identification method based on LQG benchmark,which can be used for performance assessment of various single loop controllers during coking production.The effectiveness of this method is verified through simulation examples. Theoretical improvement of the controller is given without changing the inputvariance.
