常规控制图的使用都是基于过程中得到的观测值是彼此独立的，但实际中过程出现自相关现象极为普遍。为了讨论对平稳自相关过程中出现的较小均值波动进行监控的一种方法，采用经典的自回归模型对平稳的自相关过程进行拟合，通过计算残差的方法消除过程中的自相关性，在此基础上建立了残差CUSUM控制图，并通过一个简单的例子进行说明。

The application of conventional control chart is that the observation values obtained on the basis of the pro?cess are independent,but autocorrelation appears in many processes.To discuss the method of monitoring the small mean shift in a stationary autocorrelated process,apply a classical auto-regressive model to fit the stationary au?to-correlated process,by calculating the residual to eliminate the autocorrelation of the process,and establish a resid?ual CUSUM control chart on this basis,and describe the use of this method by using a simple case.
