The Research of Hardware-in-the-Loop Simulation System Based on the Improved Dynamic Principal Component Analysis

GAO Qiang;CHANG Yong;Tianjin Key Laboratory for Control Theory & Applications in Complicated Systems,Tianjin University of Technology;  
In order to apply the data-driven technology in industry field,with the distillation column as one of the controlled objects,the hardware-in-the-loop simulation system is developed,and the data driven methods are applied to the process industry hardware-in-the-loop simulation system. Aiming at the huge computation and lowefficiency of the dynamic principal component analysis method,an improved dynamic principal component analysis method is proposed,which remove the irrelevant variables or lowrelevant variables,reduce the amount of data,and improve the diagnostic efficiency by indiscernibility and the cross-degree. For the typical faults of the systems,the application result shows that the data-driven methods can detect the fault of hardware-in-the-loop simulation system,and compared with the traditional dynamic principal component,the simulation results showthat the proposed method is more reliable with lower missing rate,and lower false rate,and in addition,it can detect the small process faults timely.
