Online Sensorless Induction Motor Temperature Monitoring

IEEE Transactions on Energy Conversion, 2010
A sensorless internal temperature monitoring method for induction motors is proposed in this paper. This method can be embedded in standard motor drives, and is based on the stator windings resistance variation with temperature. A small AC signal is injected to the motor, superimposed to the power supply current, in order to measure the stator ...

Efficient Power Control of DFIG‐Based Wind Energy Systems Using Double‐Stage Fractional‐Order Controllers Optimized by Gazelle Algorithm With Multiple Cost Functions

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Wind energy conversion systems (WECSs) require robust and efficient control strategies to ensure optimal energy conversion. This study proposes a nonlinear and resilient control approach using a fractional‐order proportional integral‐ and fractional‐order proportional derivative (FOPI–FOPD) controller for direct power regulation of a doubly fed ...

Research on Displacement Sensorless Control for Bearingless Synchronous Reluctance Motor Based on the Whale Optimization Algorithm–Elman Neural Network

Actuators
The unique structure of bearingless motors requires extra displacement sensors to monitor rotor movement, unlike conventional synchronous motors. However, this requirement inevitably escalates the cost and size of the motor. To address these issues, this

Flow‐Driver‐Generated Synchronized Nasal Intermittent Positive‐Pressure Ventilation Versus Biphasic Positive Airway Pressure After Extubation in Preterm Infants

Pediatric Pulmonology, Volume 60, Issue 12, December 2025.
ABSTRACT Objective To compare the efficacy and safety of flow‐driver‐generated synchronized nasal intermittent positive‐pressure ventilation (SNIPPV) and biphasic positive airway pressure (BiPAP) after extubation in preterm infants. Hypothesis SNIPPV delivered via a flow‐driver device improves post‐extubation outcomes compared with non‐synchronized ...
