A globally exponentially stable position observer for interior permanent magnet synchronous motors

, 2020
The design of a position observer for the interior permanent magnet synchronous motor is a challenging problem that, in spite of many research efforts, remained open for a long time.

Self-Commissioning of Inverter Nonlinear Effects in AC Drives [PDF]

, 2012
The paper presents a novel technique for an accurate identification of the inverter nonlinear effects, such as the dead-time and on-state voltage drops. The proposed technique is very simple and it is based only on a current control scheme.

Sensorless control of the synchronous reluctance motor [PDF]

Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 1994
In this paper a sensorless closed-loop speed control for the synchronous reluctance motor is presented. The sensorless control is based on the torque vector control algorithm. It has been implemented using a high-speed digital processor DSP96002. Experimental results for a 120 W axially-laminated synchronous reluctance motor are presented and compared ...

Comparison of Intraoperative Doppler Flow Measurements and Algorithmic Flow Estimations in Patients Undergoing Durable Left Ventricular Assist Device Implantation

Artificial Organs, EarlyView.
Direct intraoperative HeartMate 3 LVAD flow measurements using an ultrasonic probe revealed consistently higher values by approximately 0.5 L/min compared to device‐estimated flows. This discrepancy remained stable across pump speed settings, highlighting the importance of distinguishing measured from estimated flow in HeartMate 3 patients.

Sensorless fault tolerant control for induction motors [PDF]

International Journal of Control, Automation and Systems, 2013
In this paper, a sensorless fault tolerant controller for induction motors is developed. In the proposed approach, a robust controller based on backstepping strategy is designed in order to compensate both the load torque disturbance and the rotor resistance variations caused by the broken rotor bars faults.

A Neural Network‐Based Self‐Sensing Embedded Position Control System for Shape Memory Alloy Wire Actuators

Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.
Shape memory alloy wires exhibit thermally induced phase changes that generate actuation strain and resistance variations enabling self‐sensing. However, hysteretic electromechanical behavior complicates accurate state estimation. This paper presents an artificial in‐based self‐sensing method to reconstruct SMA actuator position in real time, achieving

Interfacial Chemistry Behind Damage Monitoring in Glass Fiber‐Reinforced Composites: Attempts and Perspectives

Polymer Composites, Volume 47, Issue 4, Page 2925-2954, 20 February 2026.
Role of the modifications at the interface in glass fiber reinforced composites for damage monitoring. ABSTRACT Glass Fiber Reinforced Polymers (GFRPs) are widely used in structural applications but degrade over time due to internal damage. Structural Health Monitoring (SHM) enables early damage detection, improving reliability and reducing maintenance
