PID  CONTROLLER LABORATORY

If you are sure that you know the mathematical model of the process, you can use the PID Control Laboratory or the PID Controller Designer. In both applets, you can define your custom transfer function and make a controller design for your nominal model. The transfer function can be specified in following forms:

SOPDT

Second order plus dead time model - gain, delay and 2 time constants

Num/Den

Gain, delay and coefficients of transfer function numerator and denominator in descending power

Zero/Pole

Gain, delay, zeros and poles of the transfer function

Bode

Gain, delay and time constants of numerator and denominator of the transfer function
