An Improved Delay-Suppressed Sliding-Mode Observer for Sensorless Vector-Controlled PMSM

This article presents a delay-suppressed sliding-mode observer (SMO) to observe the real-time rotor position of a permanent magnet synchronous machine (PMSM) controlled by vector control algorithms. First, in order to solve the low-pass filter (LPF) delay problem existing in the traditional signum f... View More
