Abstract
Stiction analysis of a conventional or legacy valve operation in a fluid process plant is described. The method includes receiving a series of setpoint signals, SP, generating, by the controller, a series of controller output signals, OP, driving the valve operation by applying the OP, to the valve, measuring a series of process variable signals, PV, downstream of the valve, receiving the series of process variable signals at the controller, performing inverse modelling on the PV, to estimate a manipulated variable,, receiving and analyzing by a system processor, the SP, the OP, and the, and outputting the estimated stick values, S, the estimated jump values, J, an average of the estimated stick values, an average of the estimated jump values, a confidence interval for the average of the stick values, and a confidence interval for the average of the jump values.
