Two digital control applications are presented: velocity control of a DC motor and adaptive system identification and control of an automotive alternator. A tuning method is proposed for DC motors. Experimental application for the DC motor illustrates the effectiveness and the simplicity of the proposed method for controller design. Using adaptive system identification, an automotive alternator...

This paper describes a 1D Matlab finite difference time-domain (FDTD) code with a graphical user interface for visualization of the time-domain electromagnetic response. The program animates time-domain reflection and transmission of a Gaussian plane wave through one or two homogeneous material slabs. ß2001 John Wiley & Sons, Inc.

MATLAB/Simulink is a popular toolset for developing embedded software. The main target of the MATLAB/Simulink toolset is numerical computing applications and the tools offer a rich language for manipulating matrices. This paper presents an approach to automatic, modular, contract-based verification of programs written in a subset of the MATLAB programming language, with focus on efficiently han...

This paper presents a compiler toolkit that addresses two important emerging challenges: (1) effectively compiling dynamic array-based languages such as MATLAB, Python and R; and (2) effectively utilizing a wide range of rapidly evolving hybrid CPU/GPU architectures. The toolkit provides: a high-level IR specifically designed to express a wide range of arraybased computations and indexing modes...

This paper is a user’s manual for MCLite, an adaptive multilevel finite element MATLAB package for solving scalar nonlinear elliptic equations in the plane. MCLite is a two-dimensional MATLAB prototype of a more complete twoand three-dimensional ANSI-C code called MC, which expends MCLite’s capabilities to elliptic systems of tensor equations on 2and 3-manifolds. Both codes share the same core ...

We present a matrix language compiler CMC which translates annotated MATLAB scripts into Fortran 90 programs. Distinguishing features of CMC include its applicability to programs with sparse matrix computations and its capability of source-level optimization in MATLAB language. Different from other existing similar translators, CMC has an ability to generate codes based on information on the sh...

Model-based design is a very popular software development method for developing a wide variety of embedded applications such as automotive systems, aircraft systems, and medical systems. Model-based design tools like MATLAB/Simulink typically allow engineers to graphically build models consisting of connected blocks for the purpose of reducing development time. These tools also support automati...

Induction motors are widely used in the industry due to its relative low cost, low maintenance and high reliability. The development of the computer and electronic industry, as well as design of new control methods, has opened the door to control induction motors. In order to control the induction motors, scalar and vector control methods are used. Vector methods have faster response and more p...

An elective course in electronic music synthesis has been developed for electrical and computer engineering students. The course provides an interesting way to integrate and apply DSP and computer manipulation concepts studied in previous courses, and extends student understanding of more advanced concepts such as time-evolving spectra. MATLAB is a standard platform used in the signals and DSP ...

High-level, numerically oriented programming languages such as Matlab, Scilab or Octave are popular and well-established tools in the scientific and engineering communities. However, their computational efficiency sometimes limits their use in certain areas where intensive numerical computations are required, such as interval analysis. In this paper, we present an efficient implementation of th...
