In this paper a module consisting of a Fast Least Mean Square (FLMS) filter is modeled and verified to eliminate acoustic echo, which is a problem for hands free communication. However the acoustic echo cancellation (AEC) is modeled using digital signal processing technique especially Simulink Blocksets. The needed algorithm code is generated in Matlab Simulink programming. At the simulation le...

Diffedge tool is a new methodology that eliminates the drawbacks of finite-difference approximations and the complexity to use the automatic differentiation. It combines the powerful of computer algebra system and block diagram structures for computing the derivative of a Simulink model with respect to the independent parameters. Diffedge calculates the symbolic derivative of the mathematical m...

Nowadays, the software for electronic control units in embedded systems is often developed using a chain of modelbased development tools. For example, in the field of automotive systems often tools like Matlab/Simulink and related code generation tools such as dSPACE TargetLink are used. To ensure that the produced models can be processed as expected by the employed tool chains, i.e., fulfill a...

This paper presents the design procedure and implementation results of a proposed software defined radio (SDR) using Altera Cyclone II family board. The implementation uses Matlab/Simulink, Embedded Matlab blocks, and Cyclone II development and educational board. The design has first implemented in Matlab/Simulink environment. It is then converted to VHDL level using Simulink HDL coder. The des...

Existing educational resources for control systems have been refined and new resources have been developed. A new LabVIEW based Control Systems Analysis Toolkit (CSAT) has been developed to assist lecturers in teaching control engineering and students to understand theoretical concepts; specific manual and activity exercises for the CSAT have been developed. An existing LabVIEW based Process Co...

We present the concept of a unified graphical environment for expressing the semantics of control systems. The graphical control system design environment in Simulink already allows engineers to insert a variety of assertions aimed the verification and validation of the control software. We propose extensions to a Simulink-like environment’s annotation capabilities to include formal control sys...

In this paper we describe an efficient methodology for rapid prototyping of data transmission systems based on Stateflow/Simulink models using a multi-level system development and testing approach. Transmission systems incorporate multi-domain functions and algorithms, i.e. physical layer circuits and communication protocol controllers. The Stateflow/Simulink environment enables the development...

A basic conceptual study of TCSC device on Simulink is a teaching aid and helps in understanding the rudiments of the topic. This paper thus stems out from basics of TCSC device and analyzes the impedance characteristics and associated single & multi resonance conditions. The Impedance characteristics curve is drawn for different values of inductance in MATLAB using M-files. The study is also h...

The approach proposed in this paper forms the front-end of a framework for the complete design flow from specification models of new automotive functions captured in Matlab Simulink to their distributed execution on hierarchical bus-based electronic architectures hosting the release of already deployed automotive functions. The process starts by deriving a task structure from a given Matlab Sim...

This paper presents the design and modeling of DC/DC boost (step-up) converter for Advanced Intelligent Systems using Matlab/Simulink.
