TLDR
A novel sliding-mode observer is built according to the back electromotive force model after the back EMF equivalent signal is obtained, and low-pass filter and phase compensation module is eliminated and estimation accuracy is improved.Abstract:
This paper proposes a novel sliding-mode observer (SMO) to achieve the sensorless control of permanent-magnet synchronous motor (PMSM). An observer is built according to the back electromotive force (EMF) model after the back EMF equivalent signal is obtained. In this way, not only are low-pass filter and phase compensation module eliminated, but also estimation accuracy is improved. Numerical simulations and experiments with an 11-kW low-speed PMSM are carried out. The results demonstrate that the novel SMO can effectively estimate rotor position and speed and achieve good static and dynamic performance.read more
