Overview
The PID Controller Characteristics trainer allows students to apply proportional (P), integral (I), and derivative (D) control modes individually and in combination to a simulated process and observe their effects on the time-domain response. A process simulator (first-order plus dead time) represents the controlled process, and step disturbances are introduced. Students tune the controller using Ziegler-Nichols and Cohen-Coon methods, observe overshoot, settling time, steady-state error, and integral windup, and optimise the PID settings for different process characteristics. The trainer builds the foundational skills needed to tune industrial PID controllers in chemical, petroleum, and utility plants.
