Predictive speed control of induction drive with high-frequency torsional oscillation

In the paper issues related to the use of model predictive control (MPC) of the drive system with an elastic coupling and an induction motor are presented. After a short introduction the mathematical model of the driving motor with a vector control structure and the two-mass drive system are described. Then, the idea of the MPC is introduced. Next the exact formulation of the MPC for a two-mass drive system is shown. In the MPC algorithm the constraints of the inner and control variables are taken into consideration. The results obtained in the simulation study confirm the correct work of the investigated structure.
