Model Predictive Control is working as a superimposed control, acting on the setpoints value of the basic control loops. Therefore the prerequisite for Advanced Process Control application is to have the base automation loops well working. This means the basic control generally implemented with PID control, should be well tuned and free from process problem as oscillations and valve sticking.
This objective is reached easily with Loop Performance Manager (LPM), supporting control engineers with two main functionalities.
- Loop Tuning - LPM help in finding the best tuning parameters for PID control
- Loop Auditing - LPM is continuously observing in background mode the loops behavior.Every week or every month LPM generates a report with indices, which show how loop performance are changing and tells if some problem occurs.
LPM is not only useful for APC applications, it is a great help to improve the performance of base loops for every type of application. Optimize IT Loop Performance Manager (LPM) is a product designed to optimize and properly maintain the base of any process automation system. Since no new equipment is required, any process plant can quickly benefit from the Loop Performance Manager without having to make a major investment.
