Abstract：The traditional multivariate statistical methods could not detect the fault effectively under the non-steady condition of complex system. For these problems above,the concept of the dynamic limit and the same peak-valley are given in this paper. And,the paper proves that the T2 statistics of the multivariable parameters is periodic if the system is under the periodic non-steady condition. Then,this paper proposes a model of real-time fault detection under the periodic non-steady condition and gives the real time and the feasibility analysis of the model. At last,the model is applied to the periodic non-steady conditions in real time.
