Proportional Kp

Derivative Kd

A PID controller drives a system to a target using three terms: proportional reacts to the current error, integral erases steady offset, and derivative damps overshoot. Tuning them trades speed against stability. Educational tool.

Governing equation

u (t) = 4 e (t) + 1 \int e d t + 1.5 \frac{d e}{d t}

Reading this result: The response never settles within ±2% — the loop is oscillatory or unstable, so back off Kp and Ki and add derivative damping.
