A Class of Time-delay Model Calculation for Grey System Modeling and Analysis

In the practical world, limited and small samples without enough information are always existed for the data measured or the system to be analyzed. Grey system is a useful processing way to study these kinds of data or system, especially for small sample data and incomplete information. Considering that time delay is existed in some system identification problems, a class of grey time-delay model was given and disused including grey time-delay model and fractional grey time-delay model. The analysis and calculation was researched by Simulink block diagram via Matlab software in the whole paper. Experiment and simulation showed the proposed time-delay grey model can be used to express the system with time-delay problem. By the Simulink block diagram, it can improve the calculation efficiency and make the results easily analyzed for complex grey models.
