| Abstract: | his paper addresses a method to estimate parameters of a cascade stable system in the frequence domain via FFT, based on the input -output data of the system. Then two second order reduced models and normalized dead-time are given. The paper also gives a PID auto-tuning formulas for controllers in the inner and outer loops. The simulation result shows the good response of the system to the setpoint change and load disturbances. |
