Enhanced PID Controllers Design Based on Modified Smith Predictor Control for Unstable Process with Time Delay
2014
Mathematical Problems in Engineering
A two-degree-of-freedom control structure is proposed for a class of unstable processes with time delay based on modified Smith predictor control; the superior performance of disturbance rejection and good robust stability are gained for the system. The set-point tracking controller is designed using the direct synthesis method; the IMC-PID controller for disturbance rejection is designed based on the internal mode control design principle. The controller for set-point response and the
