Abstract :
The optimal tuning correlations for cascade PID controllers were developed in this present work. Only the proportional gain for each controller required to be tuned, while the integral time and the derivative time for both controllers were expressed in terms of the time constant and dead time of the process models. The optimal tuning correlative formulas of the cascade controllers with respect to minimizing ISE, IAE, and ITAE were obtained through means of computer simulation
