Development of an innovative model for steady state detection in RTO loop

In order to determine the steady in a HDS RTO loop a staistical model was developed . In the developed model a set of staistical test were utilized . The utilized tests examined respectively the equality of convariance and average of two consecutive samples. if two successive samples have equal covariance and mean or different covariance and equal mean , the steady state is obtained. in order to test the reliability of the developed model two different kinds of data were utilized. in first step data were gathered from the dynamic simulaiton of bandar abbas simulation of HDS unit and in the second step the random errors were added to the data. both groups of data were test by the developed model and it reveals that the deveoloped model could detect the steady state, but when the random errors were considered in the data , the detected time of achieving to steady state is longer than the time of data which has no random errors.
