Opis:: 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.

Opis:: Position tracking systems for AC drives offering high robustness to external load torques have been presented. A triple-loop cascade control structure was employed where the inner loop is a stator current control loop and the middle loop is a speed control loop based on the forced dynamic control and respecting vector control principles. Two alternative outer position control loop designs both of which respect prescribed dynamics and settling time of position have been developed. The former system prescribes also time constant of the speed control loop while the latter one respects time constant of speed control system developed independently. To enhance the tracking abilities of both control systems the dynamic lag pre-compensator has been included. Case studies of the both position control systems for time near-optimal control and energy near-optimal control have been presented. The tracking performances of the designed control systems were assessed based on comparisons of the experimental responses with the simulated responses of the ideal closed-loop system.
