Constrained predictive control for multivariable systems with application to power systems

Generalized predictive control (GPC) and dynamic performance predictive con trol (DPC) algorithms are introduced for industrial applications. Constrain ts on plant input rate, plant absolute input and plant absolute output can be implemented and are demonstrated on an application of these algorithms. A standard quadratic programming algorithm performs the calculation of the optimal control. A MATLAB/Simulink toolbox environment has been developed w here controllers can be designed, linear and non-linear plant models can be embedded, discrete- and continuous-time loop parts can be mixed and simula tion results can be managed and evaluated by graphical and statistical tool s. This package utilises a graphical user interface. Finally, a case study design example is presented where a linear gas turbine model for power gene ration is examined with constrained GPC and DPC, and the advantages and dra wbacks of the approach are the discussed.
