How digital twins and synchronized data affect motion control

Control Design: Advancements in inverter technology, such as field oriented control and PID feedback loops, allow induction motors to achieve the high precision and efficiency traditionally reserved for servo motors.

I’m really curious about digital twins potentially becoming a more consistent aspect of engineering. I was just watching the new Stuff Made Here video where he does actually end up building a kind of digital twin in a physics engine to solve his, uh, mini golf problems. Anyway the point is that it ended up being a far more challenging task than he initially anticipated, because the many parameters needed for the simulation (as mentioned in the article) needed to be perfect in order for the real world and the digital world to line up. He initially tried to solve this with parametric estimation but no matter what he did it didn’t work, so he ended up having to adjust the parameters by hand. Seeing how difficult that project was makes me curious about how these issues would be solved by other implementations of digital twins. Though I think it would be easier for most industrial applications that aren’t so stupidly unpredictable.

I have started to become more interested with programming and coding systems for events. I have recently realized that a lot of our job as you get more and more advanced simply becomes working with computers and programming. I was drawn to this article to learn more about how physical systems work together to make things happen and their protocols that make everything work smoothly. This article highlights the importance of speccing out every parameter of a system and being able to test it virtually before implementing the real world counterpart. This is something that I have been exposed to through prediction software for speakers and some pre viz in lighting. What I noticed in this article was they they wanted every single thing represented in the model down to vibration, speed, power, and torque. I think in huge systems and event spaces this would be super important to know since there is so much going on and all the little things will add up quickly.
