Tuning for PID Controllers - Mercer University
PID Controllers • PID Controllers are everywhere! Due to its simplicity and excellent, if not optimal, performance in many applications, • PID controllers are used in more than 95% of closed-loop industrial processes. • Can be tuned by operators without extensive background in Controls, unlike many other modern controllers (Full State
