In the paperhe faults of loops for the process control system, electric actuators (valves) faults for example,established a historical fault library to diagnose the type of faults.Through system modeling method, a mathematical model analyzed the residuals robustness, which proposed a weighted moving average residuals and adaptive threshold envelope trajectory-based fault detection methods.Finally, the faults were adjusted by the active fault tolerant compensation module reasonably.
