| Abstract: | This paper combines model reduction with system identification by means of time-domain function approximation, and presents a new time domain method of direct identification of linear reduced model and model reduction, and demonstrates existence theorem of its solution and criterion of order determination. Simulation tests show that the method is simple, accurate with few data requirement. |

| Keywords: | system identification prediction approximation/model reduc-tion determination of order biosystem model estimation |
