Modeling and Simulation of Wind Energy Systems with Matrix and Multilevel Power Converters

Abstract: This paper is concerned with modeling and simulation in Matlab/Simulink of wind energy systems with different topologies for the power converters: matrix converter and multilevel converter. We use pulse modulation by space vector modulation associated with sliding mode for controlling the converters, and we introduce power factor control at the output of the converters. Finally, we present the electric behavior for the power and the current at the input and at the output of the converters.

Towards efficient design space exploration of heterogeneous embedded media systems

Abstract: Modern signal processing and multimedia embedded systems increasingly have heterogeneous system architectures. In these systems, programmable processors provide flexibility to support multiple applications, while dedicated hardware blocks provide high performance for time-critical application tasks. The heterogeneity of these embedded systems and the varying demands of their growing number of target applications greatly complicate the system design.As part of the Artemis project, we are developing a modeling and simulation environment which aims at efficient design space exploration of heterogeneous embedded systems architectures. In this paper, we present an overview of the modeling and simulation methodology used in Artemis. Moreover, using a case study in which we have applied an initial version of our prototype modeling and simulation environment to an M-JPEG encoding application, we illustrate the ease with which alternative candidate architectures can be modeled and evaluated.

Simple Modeling and Simulation of Photovoltaic Panels Using Matlab/Simulink

Abstract: This paper introduces the simple method of the mathematical modeling and simulation of current-voltage characteristics for photovoltaic panel. The aim of this modeling is to simply the nonlinear I-V model of photovoltaic panel to easily apply the model to the circuit simulators such as SPICE. So this paper is finding the parameters for the nonlinear I-V equations based on only the data such as open circuit voltage, short circuit current, voltage and current at Maximum power point and temperature coefficient for voltage and current at the nominal condition or the standard test condition which are obtained from manufacturer's datasheet.

Effective design of an assembly line using modeling & simulation

Abstract: The paper presents the results of a research work regarding the effective design of an assembly line for heaters production. Considering that the real plant still doesn't exist, simulation has been used as cognitive tool. After the modeling and the VV&A phases the simulation has been used for carrying out ergonomic analyses for each assembly line workstation. The simulation results highlight problems concerning high stress levels for some workers (due to legs bending) and ergonomic risks related to lifting tasks.
