Application of Computer Software for System Identification and PID Control Loop Tuning to a Petrochemical Plant

摘要

PID controllers are widely used in the process control industry due to their simplicity and ease of re-tuning on-line. A software package has been developed for system identification and PID control loop tuning by a partnership between UFCG and CENPES-PETROBRAS. This system implements literature and industry standard PID tuning algorithms and developed in UFCG. Application results of tuning software tools in a petrochemical plant, at PETROBRAS' are presented in this paper
