Two Torque Control Algorithms of a Synchronous Reluctance Motor Drive for the Entire Operating Speed Range

In this paper, two new algorithms for the torque control of a synchronous reluctance machine (SynRM) are proposed. The control system is set for the entire operating speed range, whereas the transition from the base speed range into the field weakening region will be the main focus of this paper. The switching strategies in the transitions phase of the two methods are also discussed using different conditions. These control strategies are evaluated using Matlab Simulink as a simulation tool followed by measurement results on an existing test bench.
