Design and Tuning Approach of 3-DOF Emotion Intelligent PID (3-DOF-PID) Controller

Abstract

This paper suggests the 3-DOF PID Controller with emotion function and tuning approach. The PID controller has been widely used owing to its simplicity and robustness invarious systems. However, the classical PID controller cannot both function such as set-point following and disturbance. To recover, the 2-DOF (Two-Degree Of Freedom) controller witha 2-DOF (Two-Degree Of Freedom) function controller which has both set point-following function and disturbance-rejecting function, at the same time has been suggested. On the other hand, emotion function is an important role in human being. However, many researchers have been dealing its structure and modeling. Herein, this paper suggests novel 3-DOF-EI-PID controller with emotion function(3-DOF-EI-PID: 3-Degree Of Freedom-Emotion Intelligent-PID). Also, this paper suggests tuning technique of the 3-DOF-EI-PID controller by immune algorithm.
