Abstract

In the paper the role of anti-aliasing filters is revised based on control quality assessment of PID controllers when using a Butterworth antialiasing filter prior to sampling versus sampling without any analog filter. Numerical results show that contrary to common belief possible benefits gained from anti-aliasing devices are very restricted.
