A Sequential Approach to the Evaluation and Optimization of Control System Performance

Evaluation of the performance of a paper machine control system was carried out using statistical methods. A sequential approach to the evaluation and optimization of control systems was used to evaluate and optimize control system performance. Time series techniques were used to determine the potential for improved process control. Spectral analysis techniques and simple open-loop process identification experiments were used to find the cause of poor control system performance. Significant improvements in control system performance were realized.
