Generalized predictive control (GPC)-ready for use in drive applications?

A usual argument against GPC is its demand for processing power. In industry, however, this is not a serious argument if better control performance can be reached. As the development of new processors with increased performance takes place rather rapidly, the lag of processing power never was a long-term issue to prevent new algorithms from being introduced. This paper presents a practical realization of generalized predictive control (GPC) for field oriented control of induction machines. The results are compared with conventional PI-control. Considering the strong real time conditions of drive applications, implementation aspects according to the great calculation effort in case of GPC are discussed to contribute to closing the gap between theory and practice
