I’m checking a Laplace transfer function that is a filtered PID version. I isolated the cause: If I remove the denominator of the equation simulation runs smoothly. I have tried rearranging the denominator, but I can’t get the simulation to run. I hope someone can help find a way to solve it.
Kelvin, thank you for helping again. The high-frequency limited PID version effectively has this form of Bode plot. The PID parameters were taken from an example in the book by Christophe Basso (2012).
