Abstract:
Stiction in pneumatically actuated control
valves and poor controller tunings are the two main
sources of performance deprivation of control loops.
The nonlinearity in control valves such as stiction is
needed to be identified quantified and compensated. A
new cohesive technique based online stiction detection
and compensation approach is introduced here. The
outcome reveals, the present method produces better
performance comparing with the existing methods.
Modeling, validation and performance of compensation
of stiction have been analyzed and verified using
Matlab/Simulink platform.
