6 Conclusion

The area of application of the model predictive controller embedded in SIMATIC PCS 7 is extended clearly by the described stabilization of unstable sub control loops with the help of a slave proportional-only controller. A typical application is an MPC where one controlled variable is the level of a tank, reactor, etc.
