Abstract
Sensorless control of the Permanent Magnet Synchronous Motor (PMSM) is a key technology for achieving high efficiency and reliable operation in Flywheel Energy Storage Systems (FESS). This review focuses on sensorless control techniques suitable for the wide speed range and high dynamic response of FESS, covering methods for zero/low-speed, medium/high-speed, and full-speed operation. First, the fundamentals of sensorless control for FESS motors (mainly PMSM) are analyzed, and the principles and advantages of high-frequency signal injection methods in the zero/low-speed range are compared, along with their limitations in standby and startup scenarios of the flywheel. Second, recent advances in model-based methods-such as sliding mode observers and model reference adaptive systems-for the medium/high-speed range are elaborated. By comparing the strengths and weaknesses of each method under charging, discharging, and standby conditions, targeted improvement strategies are summarized, and a full-speed sensorless control strategy tailored to the FESS PMSM is proposed. Finally, future trends are discussed in the context of practical FESS applications, including online parameter identification, fault-tolerant control, and the integration of intelligent algorithms.
Aiming at the problems of large starting inrush current and frequent overcurrent protection triggering under heavy load in the sensorless drive system of permanent magnet synchronous motors (PMSM) for vehicle air-conditioning compressors, this paper designs a low-cost sensorless vector controller. A back-EMF state obse...

Current source inverters (CSIs) are emerging as competitive alternatives to voltage source inverters (VSIs) for high-speed motor drives because they inherently suppress harmonic currents, offer output-voltage boosting, and reduce motor-side electromagnetic interference. Sensorless control of CSI-fed permanent magnet sy...

This study proposes an Electricity 5.0-oriented supervisory control framework for an interior permanent-magnet synchronous motor (IPMSM) drive that integrates field-oriented control, MTPA, field weakening, loss-minimization control (LMC), speed estimation, and adaptive mode selection. Four operating modes, Performance,...
Permanent Magnet Direct Current (PMDC) motors are widely used in applications requiring precise speed control due to their efficiency and high torque-to-inertia ratio. This work proposes a feedforward speed control strategy for PMDC motors based on model inversion, complemented by a disturbance rejection feedback term....
