Elucidation and Handling of Valve Actuator Nonlinearity in Process Control Loops: an Overview of Recent Results

چکیده
Valves are ubiquitous as final control elements in the chemical process industries. Motivated by heavy valve usage by the process industries and many industrial reports of valve nonlinearities undermining effective process control, this article summarizes our recent work that unifies concepts related to valve dynamics with frequently reported industrial concerns, and also investigates methods of compensating for these valve dynamics employing suitable modifications to widely-used control systems such as proportional-integral control and model predictive control.

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 کاملActive Vibration Suppression of a Nonlinear Flexible Spacecraft
In this article, the issue of attitude control and active vibration suppression of a nonlinear flexible spacecraft is assessed through piezoelectric patches as actuator and sensors. Two controller loops are applied: the inner loop, to make the panel vibration damped through piezoelectric patches; and the outer loop, to perform spacecraft maneuver using the reaction wheel acting on the hub. An o...
متن کاملControl Reconfiguration of a Boiler-Turbine Unit After Actuator Faults
Boiler-turbines are one of the most important parts in power generation plants. The safety problem in such systems has always been a special concern. This paper discusses the application of control reconfig uration by fault-hiding approach for a boiler-turbine unit. In Fault-hiding approach, after occurrence of a fault, nominal controller of the system remains unchanged; instead, a reconfigurat...
متن کاملHydraulic Linear Actuator Velocity Control Using a Feedforward-plus-pid Control
A practical approach to design a feedforward-plus-proportional-integral-derivative (FPID) controller for accurate and smooth velocity control on a hydraulic linear actuator is presented. The integrated controller consists of a feedforward loop and a PID loop. The feedforward loop is designed to compensate for the nonlinearity of the electrohydraulic system, including the deadband of the system ...
