Hi everyone
I am referring MHE CSTR case in APMonitor. 
Can you please let me know how to change the moving horizon window? I want to use different window horizons. Please advise me.

Thank you,

Jalesh,

 

You can increase it in the cstr.csv file by including additional entries in the ‘time’ column. If you don’t use a CSV file, it can be adjusted with the parameters CTRL_HOR / PRED_HOR. Here are other common tuning parameters for MHE: https://apmonitor.com/do/index.php/Main/EstimatorTuning

 

If you can switch to Python Gekko as an interface to APMonitor, it is even easier to configure MHE.

 

Best regards,

 

John Hedengren
