Abstract

In this work, a sensorless control scheme was designed for permanent magnet synchronous motors based on a sampled model. The discrete-time model was obtained using the Symplectic Euler method. Taking such model along with voltage and current measurements, an observer is designed for rotor position and velocity estimation. Then, the rotor velocity is forced to track a desired reference signal by means of a discrete-time quasi-sliding mode technique.
