Comparison of vector control methods for elimination of torsional vibrations in AC drives

The paper compares three vector control strategies for elimination of torsion vibrations. The first algorithm is based on classical IPD controller of the system with flexible coupling described in state space. The second algorithm is based on force dynamics control and the third one exploits sliding mode control. All three algorithms respect vector control of synchronous motor with permanent magnets. Matlab-Simulink environment is used to evaluate performance of all three control algorithms
