The Formal Theorem

u = P + I + D

Analytical Intuition.

PID is the Geometry of Stability. Proportional (how far), Integral (how long), Derivative (how fast). Balancing a drone or keeping a thermostat steady. Reining in oscillations.
CAUTION

Institutional Warning.

Tuning is the art. Finding the balance where the system doesn't over-correct and start shaking.

Academic Inquiries.

01

What is overshoot?

When the system moves too fast and passes the target before settling back.
