I'm pleased to see that the articles part of this workshop 3-Phase PMSM Control Workshop with NXP's Model-Based Design Toolbox have thousand of views and lots of comments. Perhaps my initial expectations were high or perhaps I was hopping that someone will glue together modules M8 with M9 and provide a final solution. Now, based on my personal experience with various motor setups and different techniques, I can honestly say that is not always easy to have such a setup working from the first try, and for each application there might be a slightly different approach, extra tuning or perhaps a trick to have it running as per expectations.Īs the current publication date of this article proves, I've also run into various issues with this application. As discussed in Module 9: Position Observer (Part 1/2) and Module 9: Position Observer (Part 2/2) there are numerous techniques for estimating the rotor speed and position and one method was chosen to be applied for our use-case. In this article we are going to discuss a couple of aspects that you should expect when building complex applications like Motor Control Speed Control of PMSM based on Sensorless methods.
