PID Controllers: Theory and Implementation

This lecture covers the theory and implementation of PID controllers, starting with the introduction of simple proportional controllers and moving on to discuss integral and derivative components. The instructor explains how to tune PID controllers using methods like Ziegler-Nichols, highlighting the trade-offs between stability, overshoot, and settling time. The lecture also delves into the challenges of implementing derivative control due to noise amplification and the practical considerations in industrial settings. The instructor demonstrates how to synthesize PID controllers using empirical rules and provides insights into the structure and tuning of PID controllers for different systems.
