PID and other controllers

00:16:17 | 27 MAR 2021
In this lecture, we will learn:
  • Compensators are sometimes given names, but just boil down to a number of poles and zeros.
  • Proportional integral derivative (PID) controllers give a pole at DC and two zeros, which can compensate one or two-pole systems (most systems).
  • Many compensators (including PID), implicitly or explicitly add a high-frequency pole to protect from unmodeled dynamics and noise.
