N2 - Cyber-physical systems (CPSs) are receiving considerable attention in recent years due to their promising benefits to the society, economy, and environment. The physical tier of industrial CPSs consists of various facilities, including perma nent magnet synchronous motor (PMSM) drives, sensors, and other embedded systems. In this paper, an advanced observer design based on higher-order sliding mode (HOSM) is proposed to achieve sensorless control of PMSM drives. The designed observer estimates the back electromotive forces (EMFs), thereby the speed of the drive can be calculated using mathematical analysis. The advantages of the proposed observer such as less chattering phenomenon, improved accuracy, and robustness, are highlighted by providing a detailed comparison analysis with the existing classical sliding mode observer (SMO) and high-order sliding mode (HOSM) observer.
