Overview

Engineering reference data for Process Controllers in process control.

Key Formulas

PID Controller

u(t)=Kpe(t)+Kie(t)dt+Kddedtu(t) = K_p e(t) + K_i \int e(t)dt + K_d \frac{de}{dt}

Proportional-Integral-Derivative control.

Transfer Function

G(s)=Kτs+1G(s) = \frac{K}{\tau s + 1}

First-order system.
