| Popis: | In this paper, a finite control set model predictive torque control of synchronous reluctance machine in the field weakening region is proposed. The machine’s future behavior is predicted for a finite set of voltage vectors that the power converter can generate, and then an optimal voltage vector is selected based on a cost function. The cost function is designed considering torque reference tracking and field weakening operation for speeds above rated, while the system constraints are handled as soft constraints and included in the cost function. The proposed control scheme is verified by simulation tests in MATLAB Simulink, and the impact of inductance error on torque reference tracking is investigated. The simulation results have shown the effectiveness of the proposed control scheme. The magnetic saturation effect of the machine is considered and incorporated into the simulations using flux maps. |
