The Research on Torsional Predictive Control of Rotary Machine

In this paper, in order suppressing torsional vibration of drive system of rotary machine, a kind of PI-DMC controller of multi-degree-of-freedom drive system is designed. Firstly, based on transfer function method, a kind of multi-degree-of- freedom drive system of rotary machine which takes into PI controller is established. Secondly, based on dynamic matrix predictive control (DMC), a kind of PI-DMC method for above multi-degree-of-freedom drive system with PI controller is designed. At last, the numerical simulation indicated that PI- DMC method can suppress torsional vibration of drive system effectively.
