Experimenting with Modified Smith Predictors Using B&R Automation Studio Target for Simulink

This paper deals with experimental verification of the new modified Filtered Smith Predictor with primary 2DOF P-controller that simplifies treatment of the control constraints carried out on a physical model of a stable optical plant using a PLC. Testing the traditional and the new solutions with different disturbance filters by real time experiments fully confirms superiority of the new controllers in constrained control. The paper simultaneously analyzes advantages of using Simulink Target for B&R Automation studio. It allows to use Matlab/Simulink environment with a PLC.
