"PROCESS AND APPARATUS FOR DETERMINING AN ESTIMATE OF A PARAMETER ASSOCIATED WITH A CLOSED PROCESS CONTROL CIRCUIT, AND A COMPUTER PROGRAM STORED IN A LEGIBLE COMPUTER FOR USE IN THE CONTROL OF A PROCESSOR". A process and apparatus that statistically determine estimates of one or more closed-loop process control parameters, such as bearing friction, seal friction, full friction, idle range, idle time, oscillation, shaft start torque or dead play , associated with a control device or closed circuit within a process control environment. The process and device measure one or more signals within a closed process control loop, when the closed process control loop is connected in line within a process control environment, store the measured signal as signal data and then perform one of a number of statistical analyzes on the stored signal data to determine the desired parameter estimate.
