“…The presented algorithm can be classified as a Direct Torque Control (DTC) algorithm, as during the control system operation an actual value of the electromagnetic torque is estimated and the torque value is controlled using simple PI regulators. This is the standard approach for controlling both asynchronous and synchronous electrical motors [23]. To operate, the proposed control system requires the values of phase currents and the position and angular speed of the rotor of the machine.…”

The Synchronous Reluctance Machine (SynRM) is an electrical machine in which the useful electromagnetic torque is produced due to rotor saliency. Its high powerand torque-to-mass ratio and very good efficiency make it a cheap and simple alternative for permanent magnet or induction motors, e.g. in electromobility applications. However, because of magnetic nonlinearities, the rotational speed and torque control of a SynRM is a nontrivial task. In the paper, a control algorithm based on a Hamiltonian mathematical model is presented. The model is formulated using measurement results, obtained by the drive controller. An algorithm is tested in the drive system consisting of a SynRM with the classical rotor and a fast prototyping card. The drive dynamic response in transient states is very good, but the proposed algorithm does not ensure the best efficiency after steady state angular velocity is achieved.
