Abstract:
When a pract ical sy stem is discer ned, it s const ruct ion is o ften not known. Therefo re, if the system parameters ar e to discern, the order of the system must be discerned at the same time. In the paper , according to analy sis theor y of linear system in the fr equency domain, the discernment method of linear cont inuous-t ime system is discussed, including integral link, and the implement procedur e of order discernment o f linear system, the steps of discerning model const ruct ion and the way o f designing pro gram w ith F test metho d. It has been made clear f rom the experiment result that the metho d has a certain discernment precisio n and eng ineering application value.
