A segmentation-based approach for detection of stiction in control valves
نویسندگان
چکیده
A method for detecting static friction (stiction) in control valves is proposed. The method is model-based and is inspired by ideas from the fields of change detection and multi-model mode estimation. Opposed to existing methods only limited process knowledge is needed and it is not required that the loop has oscillating behavior. The advantage of the method is illustrated in both numerical simulations and evaluations on real loop data.

Fuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve
Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...
متن کاملStiction identification in nonlinear process control loops
Nearly 20-30% of all process control loops oscillate due to stiction and lead to loss of productivity. Thus, the detection and quantification of stiction in control valves using just the raw operating data is an important component of any automated controller performance monitoring application. Many techniques have been proposed for the detection and quantification of stiction. Pattern based id...
متن کاملDetection and Quantification of Control Valve Stiction
Stiction is one of the most common problems in the spring-diaphragm type control valves, which are widely used in the process industry. Although there have been many attempts to understand and detect stiction in control valves, none of the current methods can simultaneously detect and quantify stiction. There is thus a clear need in the process industry for a non-invasive method that can not on...
متن کاملA new stiction compensation method in pneumatic control valves
AbstractIn this paper, a new compensator is designed so as to eliminate the effect of stiction in the control loop. A wellknown stiction compensation method is proposed that reduces variability both at process variable and valve stem movement. Pneumatic control valves are widely used in the process industry. Stiction is the most common and one of the long-standing problems in the pneumatic cont...
متن کاملParameter Estimation of Valve Stiction Using Ant Colony Optimization
In this paper, a procedure for quantifying valve stiction in control loops based on ant colony optimization has been proposed. Pneumatic control valves are widely used in the process industry. The control valve contains non-linearities such as stiction, backlash, and deadband that in turn cause oscillations in the process output. Stiction is one of the long-standing problems and it is the most ...
