I'm currently building an inverted pendulum for a final project and I'm running into some problems.
There is aton of noise on all of the voltage supplies from the pwm switching and it is making it difficult to measure some rotary encoder signals.
I tried using optoisolators, but my encoder signals are too fast to use them.
(the pendulum encoder has a pulse width of 5us).
Any suggestions on how to remove some of this noise?
I'm using these chips https://www.electro-tech-online.com/custompdfs/2006/12/ir2184.pdf to drive the bridge and it says that they have a seperate power and logic ground, but I cant seem to get it to drive the highside fet with the grounds seperate. Anyone familar with using this IC?
