Bode-Like Control Loop Performance Index Evaluated for a Class of Fractional-Order Processes

Popis výsledku v původním jazyce

Control loop performance assessment techniques are crucial for optimizing any plant or machine. They can bring huge energy and material savings and increase product quality. Usually, the performance is compared to minimum variance controller. It is knownthat when optimizing process controllers having xed structure (e.g. PIDs) dierent concepts must be applied. In this paper, the systematic approach for a class of fractional-order processes is presented. Inspired by the model free design techniques, onlya minimum a priori information about the process is assumed. A novel performance index based on 'ideal' shape of sensitivity function is proposed. Two fundamental limits are considered: available loop bandwidth and robustness MS-index. The best possibleperformance is computed for all processes belonging to the fractional-order model set controlled by PID-type controllers. The authors believe that the presented ideas may be utilized by both academic and industrial sphere.
