You are using the same parameter you are trying to estimate as the feedback for the Observer, this to me means that the Observer will converge to your estimate and therefore the entire Observer could be replaced by the estimate based on the change in resistance and perhaps a filter. Maybe I misunderstood something but to me this seems like the Observer only acts as a filter for the ”open loop estimate”.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-910685024071367839.post-21312462672218091042019-11-13T00:14:39.554-05:002019-11-13T00:14:39.554-05:00Very cool!
I think you mixed up thermal conductivi...Very cool!<br />I think you mixed up thermal conductivity with thermal resistance. The rest of the derivation should be the same, but yeah just a notation issue.<br />$\dot{Q_{out}} = R_{th} \Delta T$ If thermal resistance goes up, the heat dissipation should go down.<br />Nice writeup!madcowswehttps://www.blogger.com/profile/06218445216086016712noreply@blogger.comtag:blogger.com,1999:blog-910685024071367839.post-74927679303424039462019-11-03T09:19:35.293-05:002019-11-03T09:19:35.293-05:00Hey Ben,
