Hello,
I'm building a model of an accelerating engine in SimuLink, and based on real logged data I want to approximate my parameters (Cd, rolling coefficient) such that they reflect reality. To achieve this I'm using the Control and Estimation Tools manager. I think is a suitable tool but I have some problems with the implementation. The examples I've found on internet all concern an input-output based situation, such a DC engine. However, the nature of my model is a bit different. I just supply initial conditions (entry speed, gear etc.) to run the simulation. As such, I do not have a clear input-output model that i can specify for the optimizer, and thus the parameter optimizer says that the object function is in a local minimum.
I hope it's a bit clear what I mean, and you can help me out 🙂
