Magnetic pulse welding (MPW), Crimping (MPC) or forming (MPF) are very promising technologies based on pulsed magnetic field using a magnetic pulse generator. This paper aims to study the current and temperature distribution produced by an intense pulsed current in a massive one turn coil. The study involves a 3D numerical simulation model of the coil in LS-DYNA® based on Maxwell equations and Finite...
Nowadays, the electricity demand in remote areas is increasing. Among a variety kinds of renewable energy sources, wind energy is very used. This type of energy presents a realistic alternative for power production. Therefore, to ensure optimal use of this energy, different control strategies are well studied in the literature. In this work, an autonomous wind energy conversion system based on a double...
In this article, a novel sensorless speed control based on the combination of a linear Quadratic Regulator (LQR) and a PI controller is proposed. the proposed control technique has two principal aims; (i) overcome the system uncertainties and, (ii) achieve an accurate control performance. The use of above regulators in this hybrid control method is argue by the fact that a LQR has a very easy structure...
This paper presents advanced power management strategy for a stand-alone hybrid power system. The proposed system consists of a photovoltaic panel, Proton exchange membrane fuel cell and a battery-electrolyzer-super capacitor energy storage system. All the system components are connected to the same DC voltage bus through appropriate Dc-Dc power converters and supposed to be controlled by independent...
This paper, deals with a new input-output sliding mode linearization control for induction motor combined with field oriented control (FOC). To control the speed and rotor flux modulus, we develop two loops. The first one, inner loop, allows to linearize the system by a choose of closed loop poles to achieve a good linearization. The choice of a particular sliding surface permits to create a link...
This paper presents a robust voltage control intended for a photovoltaic system, the main objectives of the proposed control is to adapt with the parameter variations and load disturbances. Second order sliding mode controller, based on super twisting algorithm for DC-DC Buck converter is proposed. Applying SOSMC can improve the transient response of the system for a wide range of reference voltage...
This paper deals with a comprehensive supervisor control for a hybrid generation system. Such system works in island mode and comprises a photovoltaic panel and a battery/super capacitor energy storage system. The principal aims of the proposed supervisor are, firstly, to control the energy flow of the system in order to satisfy the load power demand, secondly, to manage the loads according to the...
