EV powertrain controller for max acceleration performance PMSM

881 Views 3 Replies 3 Participants Last post by  TopGearFan
Hello!
I'm looking to design and simulate a simple but efficient powertrain controller for a PMSM, aimed only to achieve the max performance on the acceleration event. It's a field out of my comfort zone, but regardless this being only for educational purposes, I would like to idealize and design a competitive solution aimed only for maximizing the acceleration. My initial idea is a controller including a closed-loop control of MTPA (maximum torque per ampere) combined with flux weakening control. All in addiction with a PID controller to minimize time reaction. Furthermore, I thought it could be beneficial if i switch from an open-loop control to a closed-loop control after reaching 20% of the nominal velocity.
What are your thoughts on that?
Any suggestions or documentation that you could provide about the topic?

Thank you!

Add a pair of drag slicks and you're breaking gears and axles.

In an EV, acceleration is not a problem. Traction is.

Even the little Bolt EV can be quite annoying by breaking the tires loose from a standstill when you're aggressively pulling into traffic.

As far as your academic research, YOU, not the Internet, are supposed to do the heavy lifting and find your own research papers.

If you don't learn how now, you will be worthless when you try to get a day job.

thank you for the reply. I appreciate the feedback. Guess i didn't take into consideration physical consequences of forcing a fast and steep response.

Sometimes I think I didn't choose the best department in college for my education. For several years I wanted to become a chef and study cooking in college. I enjoyed exploring different types of food https://samplius.com/free-essay-examples/different-types-of-food/ coming up with healthy and tasty recipes. But on the advice of my father, I still chose the Faculty of Engineering. And despite the fact that the tasks are quite interesting, they are too difficult for me. Hopefully I can find some advice on this forum as I'm almost out of ideas.
Thank you!
Wow! looks like a very cool project, if this is an educational project then maybe you are studying what you like) You must be a great engineer.

Reading such topics, I once again rethought that I had chosen the wrong faculty at the university. I find my studies boring. I hope I will see the continuation of your theme and the project will be completed as you planned!
