摘要
A method and apparatus statistically determines estimates of one or more process control loop parameters, such as bearing friction, seal friction, total friction, dead band, dead time, oscillation, shaft windup or backlash associated with a device or a control loop within a process control environment. The method and apparatus measures one or more signals within a process control loop when the process control loop is connected on-line within a process control environment, stores the measured signal as signal data and then performs one of a number of statistical analyses on the stored signal data to determine the desired parameter estimate.
