Abstract :
With the long-term aim of providing each control system with its own diagnostic capability so that it is not only self-validating, but also able to isolate in-process faults that affect the control system, this paper describes a steady state procedure for isolating faults in plants with control loops that inherently eliminate steady state error. The procedure is tested on a simple continuous stirred tank reactor simulation
