Simulink using with fmincon
显示 更早的评论
Hello guys. I would like to ask you about how to use fmincon to optimize simulink model.
I have a function that returns scalar constant that i want to minimize. I get this constant from simulink but, when i use fmincon to optimize model parameters to minimize this constant. It is changing parameters in workspace but simulink always returns the same scalar constant like if it wouldn't change at all.
How can i force matlab to change this constants inside if simulink while fmincon is running?
Here you can see that i'm using fmincon on minimisation_of_vibration_absorber function
in this function i linearize simulink model and geting transfer function numenator
red blocks are blocks that have parameters defined in workspace that i would like to optimize
Every time my optimization function fmincon returns absolutely unchanged numenator even if constants has been changed in workspace.
Thank you!

Perhaps you can look at some worked examples and figure it out:
Good luck,
