Description

As you can see in the design of the package, the low pass filtered velocity error is only used in the calculation of the derivative output of PID. However, in code, P, I, and D are calculated by using filtered velocity error.

I think it's fine to apply LPF to all the P, I, and D to make each of them stable. Just updating the figure in the design would be enough.
