11.3 PID and other controllers
2021년 3월 27일
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.
