Error in Example 02 when AEP is selected for merit figure #226

Closed HCKimDaniel closed 1 year ago

HCKimDaniel commented 1 year ago

Hello,

I am running Example 02 for controller optimization. I wanted to compare the optimization results between three merit figures, which are AEP, DEL_RootMyb, and DEL_TwrBsMyt. If I select DEL_RootMyb or DEL_TwrBsMyt, it works well, but if I select AEP, it has an error as below. Can you help me for removing this error? Thank you for your time.

This example does not use much of WISDEM, including the rotorse module. That is why the response is missing.

You will need to add the objective, like it is here, on the weis pose optimization method, with aeroelastic.AEP as the objective. It's probable that you'll also need logic to detect which objective to actually use within openmdao, or it will try to have both.

It's also likely that using AEP as a merit figure, without constraints on loading, will give you a controller that does not work well and may be unstable. Though if you keep the constraint on the generator speed, that should keep things somewhat stable.

Thank you for your answer. I will try it.

@dzalkind Thank you! It works well with aeroelastic.AEP
