Abstract: A method of performing online diagnostics for a valve includes receiving valve information while the valve is in operation. The valve information includes setpoint data and position data associated with the valve. The method further includes processing the setpoint data and the position data at a plurality of time intervals, and detecting an occurrence of a stick-slip based on the processing.
