IMPLEMENTATION OF PREDICTIVE MULTIVARIABLE DMC CONTROLLER IN A PILOT PLANT

This study aims to implement the predictive multivariable DMC controller in a real plant and compare it to multi-loop PID. The practical application is made in a pilot plant located in the IFES / Serra, where pressure and level are controlled with pump speed and valve opening. Tuning of the DMC controller is obtained through a simulator based on genetic algorithm. The plant responses to step using multi-loop PID and DMC are compared with and without constraints on valve opening and pump speed. The DMC controller is also tested with output restriction (pressure and level). The didactic interface developed with LabVIEW software is used to interact with MATLAB and CompactRIO controller, allowing the use of MATLAB optimization functions in the implementation of the DMC controller.
