| Abstract: | To overcome the deficiencies addressed in the conventional PID control and improve the dynamic performance and robustness of the system,a simple design and parameters tuning approach of internal model control-PID(IMC-PID) controller was proposed for the first order plus time-delay(FOPTD) process and the second order plus time-delay(SOPTD) process.By approximating the time-delay term of the process model with the first-order Taylor series,the expressions for IMC-PID controller parameters were derived,and the... |
