Predictive Control; Non-Minimum Phase System; Prediction Horizon; Constraints; Optimization

A predictive controller is a modern type of a regulator which is appropriate for many characters of processes. Non-minimum phase systems contain an undershoot in the initial part of its dynamic behaviour. The traditional approach in predictive control of non-minimum phase systems is based on increasing of the minimum prediction horizon. This method may not be always absolutely effective. In this paper there is proposed an approach which is based on manipulating with constraints in an optimization subsystem. In the paper are also evaluated simulation results.
