Implicit Euler Discretization for Enhanced Sliding Mode Observer in Sensorless Permanent Magnet Synchronous Motor Control

This paper presents a discrete-time sliding mode observer designed to estimate the rotor position of PMSMs for sensorless control strategies. Without compromising the sliding feature, this study employs a discretization method known as implicit Euler discretization, converting the set-valued functio...
