O Tempo de Corte com Discos Abrasivos Pode Ser Reduzido pelo Controle da Velocidade de Corte
(1997-12-01)
This work presents an experimental study on the life of abrasive discs in cut-off type operations with two conditions of cutting speed. The cutting time is shown with a comparative analysis of the cutting speed.
Quality of mechanical soybean harvesting at two travel speeds
(2017-01-01)
Soybean harvesting is the last operation performed in the field and therefore has high added value. Quantitative losses during this process should therefore be minimized to achieve maximum quality and increase the ...
QUALITY OF MECHANICAL SOYBEAN HARVESTING AT TWO TRAVEL SPEEDS
(Soc Brasil Engenharia Agricola, 2017-11-01)
Soybean harvesting is the last operation performed in the field and therefore has high added value. Quantitative losses during this process should therefore be minimized to achieve maximum quality and increase the ...
Comparison of the performance and energy consumption index of model-based controllers

Self-Tuning Resonant Control of a Seven-Leg Back-to-Back Converter for Interfacing Variable-Speed Generators to Four-Wire Loads
(IEEE, 2015)
This paper considers the control of a seven-leg back-to-back voltage source inverter arrangement, feeding a four-wire load from a three-phase permanent-magnet synchronous generator (PMSG) operating at variable speed. The ...
Digital control and integration of a 192 MW wind farm with doubly fed induction generator into the Brazilian power system
(ELSEVIER SCIENCE SA, 2010)
This paper reports on design of digital control for wind turbines and its relation to the quality of power fed into the Brazilian grid on connecting to it a 192 MW wind farm equipped with doubly fed induction generators. ...
CONTROL STRATEGIES FOR POWER SMOOTHING USING A FLYWHEEL DRIVEN BY A SENSORLESS VECTOR-CONTROLLED INDUCTION MACHINE OPERATING IN A WIDE SPEED RANGE
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS, 2004)
Controlling open quantum systems using fast transitions
(American Physical Society, 2013-02-13)
Unitary control and decoherence appear to be irreconcilable in quantum mechanics. When a quantum system interacts with an environment, control strategies usually fail due to decoherence. In this article we implement a ...
Time-optimal control fields for quantum systems with multiple avoided crossings
(American Physical Society, 2015-10)
We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optimal ...
