Process Controller Performance Monitoring and Assessment
نویسنده
چکیده
Estimates of the percentage of industrial process controllers with performance problems are surprisingly high – various studies indicate that anywhere from 66% to 80% of controllers are not performing as well as they should. These controllers can have a significant detrimental effect on plant profitability, both in increased product variance and increased reaction times. In addition, the regulatory control layer is the foundation of all advanced applications; without a well tuned regulatory layer, DMC’s, RTO’s, ERP’s, etc. can (and often do) fail.

متن کاملAssessment of Tuning of Pi Controllers for Self-regulating Processes
A method for the performance assessment of Proportional-Integral (PI) controllers for single-input single-output (SISO) self-regulating processes is proposed. In particular, the effectiveness of the tuning of the controller with respect to its load disturbance rejection performances is determined by evaluating simultaneously different simple indexes that are calculated by considering only the m...
