ABSTRACT: This paper presents a
robust sixth-order Discrete-time Extended Sliding Mode Observer (DESMO) for sensorless
control of PMSM in order to estimate the currents, speed, rotor position, load
torque and stator resistance. The satisfying simulation results on Simulink/Matlab
environment for a 1.6 kW PMSM demonstrate the good performance and stability of
the proposed ESMO algorithm against parameter variation, modeling uncertainty,
measurement and system noises.
