What I understand from the assignment is I have to make the VB code in file nu1. xlsm generic, and run several iterations for Kc and Ti to find out the optimal combination which will result in minimum error value and convergence.
The process coef. a and b in equation y = a * y + b * u will be 0.7 and 0..4 respectively as mentioned in the word doc.
After I run various scenarios for Ti and Kc, I will write a short paragraph on how does change in Kc changes the error value (first it decreases, reaches minimum and starts increasing again...), and similarly for Ti.
I will deliver an excel file with various scenarios tested and optimal scenario highlighted, and a word document as the output files. Please let me know if this is fine.
