In this work a discrete-time model for Permanent Magnet Synchronous Motors (PMSM) is proposed based on the Symplectic Euler method. Open-loop simulations predict that the discrete-time model obtained via the Symplectic Euler method performs better than the discrete-time model obtained with the classical Explicit Euler method. Then, a discrete-time sliding mode controller is designed for the model obtained via the Symplectic Euler method for the tracking of the rotor velocity. A closed-loop simulation of the continuous-time plant with the discrete-time controller is carried on for the verification of the good performance of the discrete-time model and control scheme.
