Abstract:
A method of determining a segment-specific estimate of a parameter associated with a process control loop includes receiving signal data corresponding to a signal from a process control loop, storing the signal data, partitioning the stored signal data into a plurality of data segments and performing a statistical analysis on a first one of the plurality of data segments selected from the plurality of data segments to generate a first segment-specific parameter estimate.
