The electromagnetic field is an interest scientific subject on overhead transmission lines OTL under high voltage for the reason of their risk on the living organisms such as blood leukemia and others. The aim of this paper is to calculate the electric potential, electric field and the magnetic field around and near of high voltage transmission lines using The ComsolMultyphisics program package based...
In this work, the authors introduce a non stationary time-frequency domain decomposition technique for modeling high resolution sea backscatter. In doing this, empirical mode decomposition (EMD) method is applied firstly for denoising the in-phase and the quadrature-phase components. Then, the maximum likelihood estimation (MLE) method is employed in the intensity domain to estimate the shape and...
This paper deals with the detection and localization of electrical drives faults, especially those containing induction machines. First, the context of the study is presented and an Extended Kalman Filter is described for induction machines fault detection. Then the modeling procedure under faulty conditions is shown, and the machine diagnosis methods are developed. The proposed diagnosis approach...
The paper present an architecture multi-controller based in conventional PID controller and robust Fractional PID controller (FOPID) using PSO algorithm to optimize the parameters of PID and FOPID, and improved the robustness. This approach applied to control robotics wrist (Robot RX-90 Staübli). A brief overview of the process with a non-linear and linear mathematical modeling of the process. Principle...
The paper presents a new multi-controllers approach with H∝ control applied to control a manipulator robot wrist (Staubli RX-90). A brief description of process and linear mathematical modeling of the process. Principle of multi-controllers approach of control is briefly presented. Our new proposals concerning the type of the controllers used in the multi-controller approach of control and which are...
