Design and Development of Universal On Line Auto Tune PID Controller

Abstract — this paper presents the development of a universal on-line version of auto-tuning proportional-integral – derivative (PID) controllers based on the successive approximation method. The new universal controller causes only minor perturbation on the normal operation of the process, needs little a prior information, and is robust to noise. The performance and design for automatic selection of the PID constants are discussed for any system. The accuracy and performance of this new universal on-line version of auto-tuning method have been substantiated by extensive lab Index Terms — Auto tuning, PID Controller, successiv
