Learning PID Tuning I: Process Reaction Curve

process reaction curve approach to tune PID controller

Process reaction curve approach to approximate high-order (linear or nonlinear) systems with a first-order-plus-timedelay model using step response data. It also provides an example of PID controller design using the approximate model based on the classical tuning table. It can be easily replaced with any other more advanced tuning tables based on the same approximate model.
