I have implemented a control algorithm and I would like to study its performance by looking at the trend of the tracking error and then algebraically transpose what I visualize, I have thought to use the RMSE. This kind of error anyway penalizes the big errors, that in my case there are in the transient state, i.e. when the algorithm starts.
Is it a good idea to exclude the transient in the RMSE calculation?
I mean: is it normal that at the start of the algorithm the error reaches peaks and then it goes to 0?
