Sensorless control of the synchronous reluctance motor [PDF]
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 ...

Vehicle Mass and Road Gradient Identification by Extended Kalman Filter Based on Mass Pre‐Estimation
Vehicle mass and road gradient identification by extended Kalman filter based on mass pre‐estimation. ABSTRACT Information on road gradient and vehicle mass is critical for the performance of the automatic shift system. This study presents a real‐time identification method for estimating vehicle mass and road gradient using an extended Kalman filter ...

Speed Estimators Using Stator Resistance Adaptation for Sensorless Induction Motor Drive
The paper describes speed estimators for a speed sensorless induction motor drive with the direct torque and flux control. However, the accuracy of the direct torque control depends on the correct information of the stator resistance, because its value ...

Sensorless fault tolerant control for induction motors [PDF]
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.

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 ...

Sensorless Finite-Control Set Model Predictive Control for IPMSM Drives [PDF]
This paper investigates the feasibility of a sensorless field oriented control (FOC) combined with a finite control set model predictive current control (FCS-MPC) for an interior permanent magnet synchronous motor (IPMSM). The use of a FCS-MPC makes the implementation of most of the existing sensorless techniques difficult due to the lack of a ...

A Review on Kinematically Redundant Parallel Mechanisms With Configurable Platforms
This review systematically combs the development context and technical system of Parallel Mechanisms with Configurable Platforms (PMCPs). Furthermore, through the progressive logic of classification, analysis and application, the paper reveals how “kinematic redundancy” and “configurable platform” break through the rigid limitations of traditional ...

Sensorless variable impedance compliant control for human–robot interaction
In order to improve compliance in human–robot interaction, a sensorless variable impedance control method is proposed. Variable impedance control is constructed using the end-effector velocity and the human–robot interaction force.

Reconfigurable Haptic Feedback: Comprehensive Design and Control Framework
Herein, a modular framework is presented for designing and controlling soft robotic haptic devices capable of shape and stiffness modulation. These reconfigurable modules enable adaptable tactile feedback for virtual reality and assistive rehabilitation. Two use cases are demonstrated and it is shown how minimal sensing, combined with machine learning,
