The pervasive use and performance problems of Proportional-Integral-Derivative (PID) controllers in the process industry sector prove that the implementation of a PID Control Performance Improvement (PCPI) system is a value-adding activity. This article, based on the limitations of the existing control loop performance-monitoring tools, approaches PID control performance from an improvement perspective. An integrated framework for PCP system development in the measure-diagnose-correct logical sequence is proposed. The various tools required for each phase, user interface requirements, and effectiveness of object-oriented system modelling are presented. Based on the proposed framework, a decision support system is developed for PID control. The application of the system to performance analysis and corrective action of a vulcanization process control proved substantial scope for performance improvement, thus validating the proposed framework.
