Using Electric Current as a Weed Control Method
European Journal of Engineering Research and Science, 2017 Weed struggle has an important place in agricultural production. The widespread use of chemicals in this struggle is due to its easy applicability, its short-term results, and its economic efficiency. However, the negative effects of these chemicals on the environment and human health have been recognized, and the interest in non-chemical struggle ...

Current Tracking Adaptive Control of Brushless DC Motors
International Journal of Adaptive Control and Signal Processing, EarlyView.In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Magnetic noise controlled by electric current through core
Electronics Letters, 1980 Magnetic noise in tape cores can in general be suppressed considerably by passing suitable galvanic currents through them. The method is also applicable to samples subject to asymmetric shear twist forces. A linear decrease in peak-to-peak maximum magnetic noise is observed for increasing currents through the core for the amorphous ribbon Fe80B20.

Controlled motion of electrically neutral microparticles by pulsed direct current [PDF]
Scientific Reports, 2015 AbstractA controlled motion of electrically neutral microparticles in a conductive liquid at high temperatures has not yet been realized under the uniform direct electric current field. We propose a simple method, which employs pulsed direct current to a conductive liquid metal containing low-conductivity objects at high temperature.

Maximum Torque Per Ampere Control Strategy of a 5-phase PM Generator in healthy and faulty modes for tidal marine turbine application [PDF]
, 2014 The work presented in this paper aims to propose a control strategy being able to extract efficiently energy from a fixed-pitch marine current turbine associated with a 5–phase Permanent Magnet Synchronous Generator (PMSG) in healthy mode and in faulty ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.
