MATLAB offers an attractive interface for sequential simulation.  Amoung other activities, sequential simulation can be used for replay of historical data or studies for controller tuning.  The file parsing and trending capabilities allow results to be visualized in a flexible computing environment.

Sequential simulation refers to the method of data access.  Instead of a single simulation, the sequential approach takes a set of new information and re-runs the calculation.  Model replay also allows application behavior to be investigated before placing it on-line.  Model changes can be investigated over the same data period with this approach.

ModelReplay is a user-built MATLAB script that acts as a user interface to handle sequential runs of the command-line version of APMonitor. The latest script file is designed only for moving horizon estimation but may be extended for dynamic simulation or nonlinear control in future versions. Primary actions performed by the script file at each time step are APMonitor.exe execution, file/folder management, Database File (dbs) updates, and presentation of results.

Attach:modelreplay.png

Several built-in MATLAB functions were used to facilitate string, file and folder handling: copyfile, dlmread, importdata, num2str, rmdir, strcat, strcmp, strmatch, strrep,  strtrim, textscan. Cellwrite.m is a user-built function that allows MATLAB to convert textscan output back into a text file and can be found on the MathWorks website.

Key configuration parameters to set in any user-built APMonitor interface:
* NLC.DIAGLEVEL : specifies type and number of files output by APMonitor into the local directory.  Diaglevel = 0 outputs the minimum essential files while DIAGLEVEL = 5 performs the greatest number of diagnostic checks.
* NLC.COLDSTART : should be set equal to 1 when starting from a cold start and set equal to zero afterwards to 0 for a warmstart. A cold start is the first run of past measurements. A warm start assumes more than one past time-step of measurements are available.
* NLC.DBSREAD and NLC.DBSWRITE : should both be set equal to 1 to interface with DBS files.
* NLC.IMODE : sets the analysis mode.
* {MV or SV}.MEAS and {MV or SV}.NEWVAL: update the .dbs file with the current measurement.

ModelReplay may be applied in an industry setting to predict the response of an estimation or fault detection algorithm with varying unknown model parameters over a variety of past operating conditions.

!!!! File/Folder Management

Essential files such as est.t0, est.meas, est.dxdt, and .dbs files are copied into the new run directory prior to APMonitor execution.  New folders are created and older folders are deleted based on setting found in ModelReplay.m.
