Abstract: To get the exact model,the simulation research for process identification in multivariable open-loop paper-making process is done.It is concluded that the sampling time of identification has tied in with the model’s constant time and prolonging the sampling time can improve the accuracy of identification.

Key words: multivariable, identification of paper-making process, open-loop identification, sampling time
