APPARATUS AND METHOD FOR ACTUATOR PERFORMANCE MONITORING IN A PROCESS CONTROL SYSTEM |
摘要 |
<p>A method, apparatus, and computer program are provided for actuator performance monitoring. A test of an actuator (116-124) in a process control system (100) can be initiated, such as when a break in the operation of the actuator (116-124) or a machine (102) associated with the actuator (116-124) is detected. The test could include providing a varying control signal (such as a varying pressure signal) to the actuator (116-124). A response of the actuator (116-124) to the control signal is analyzed to determine if the actuator (116-124) is suffering from one or more faults. Analyzing the response could include generating a first pressurization curve identifying how a pressure in the actuator (116-124) varies over time in response to the pressure signal. Analyzing the response could also include comparing the first pressurization curve to a second pressurization curve, such as a baseline pressurization curve generated when the actuator (116-124) was first commissioned in the process control system (100).</p> |
