Detection of Oscillating Control Loopssence of oscillations in a control loop increases the deviations from the setpoint of the process variables, thus causing inferior products, larger rejection rates, increased energy consumption and reduced average throughput. There are several reasons for oscillations in control loops. They may be c

Curve Fitting for Detecting Valve Stiction by using any of the oscillation detection methods presented in Chap. 4. The stiction-detection method is based on the curve-fitting results of the output signal of the first integrating component located after the valve, . the controller output for self-regulating processes or the process output fo
