Since the question is back here and open, there is nothing you need to do. As for the general on-topicness of questions on Kalman filters, they're absolutely on-topic, no doubt about it.
However, you should pause to think as to why your question might have attracted close votes. See the first version of your question that you asked. Now that is hardly a meaningful question! Your next reasonable update came 10 hours later and in the mean time, it attracted close votes because it could not have been answered in its (then) current form.
I can't speak for phonon, but looking at the version just before migration, he must have gotten the impression of it being a physics question where you're trying to model the equations of motion. It seemed that your question was not about the state equations, but rather if you've modeled the physics correctly. So given the existing close votes, he must have migrated to save the question.
In future, I would recommend being more upfront about the topic and describe the problem in clear terms. At present, it looks like streams of thought written down as they came to your mind, but it could be improved by restructuring it by:
- Very briefly mentioning the general topic in a line or two (What is it about?)
- Identifying the problem (Where are you stuck?)
- Showing some effort (What have you done?)
- Adding minimal working example or additional data (Do you have something more to add to this?)
I know you have done all these somewhere in the question, but it's hard to search for them :) Clearly focusing on getting these points across will help us understand what you're asking and also let us know what you need help with.
