Speed adaptation as Kalman filtering
(Pergamon-Elsevier Science Ltd, 2008-10)
If the purpose of adaptation is to fit sensory systems to different environments, it may implement an optimization of the system. What the optimum is depends on the statistics of these environments. Therefore, the system ...
Translation and cross-cultural adaptation of the Detailed Assessment of Speed of Handwriting 17+ to Brazilian Portuguese: Conceptual, item and semantic equivalence
(2018-01-01)
Purpose: Perform a cross-cultural adaptation of the Detailed Assessment of Speed of Handwriting 17+ (DASH 17+) for Brazilians. Methods: Evaluation of (1) conceptual, item and (2) semantic equivalence, with assistance of ...
Smart Algorithms to Control a Variable Speed Wind Turbine
In this paper, a robust adaptive fuzzy neural network sliding mode (AFNNSM) control design is proposed to maximize the captured energy for a variable speed wind turbine and to minimize the efforts of the drive shaft. Fuzzy ...
Closed-loop adaptive high-starting torque scalar control scheme for induction motor variable speed drives
(MDPI, 2022)
This article proposes a closed-loop (CL) high-starting torque (HST) scalar control scheme (SCS) for induction motors (IM). It endows the recently proposed HST-SCS with high-output torque capability beyond starting after ...
An ice machine adapted into an autonomous photovoltaic system without batteries using a variable-speed drive
(JOHN WILEY & SONS LTD, 2010)
The adaptation of a commercially available ice machine for autonomous photovoltaic operation without batteries is presented. In this adaptation a 1040 W(p) photovoltaic array directly feeds a variable-speed drive and a 24 ...

An adaptive feedback linearization strategy for variable speed wind energy conversion systems
(John Wiley & Sons Ltd, 2000-02)
This paper presents a control strategy based on adaptive feedback linearization intended for variable speed grid‐connected wind energy conversion systems (WECS). The proposed adaptive control law accomplishes energy capture ...
Adaptive full-order observer analysis and design for full-range sensorless interior permanent magnet synchronous motor drives
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-10-22)
This Thesis presents contributions to the study, development, analysis and design
of adaptive observers applied to the estimation of rotor position and speed of interior
permanent magnet synchronous motors (IPMSM). The ...
