Simulation Tools

Anatasia Veloni, Alex Palamides
In this chapter, we introduce the following simulation tools: MATLAB® is a Mathworks product. It is a very popular software tool designed for scientific and engineering computing. It comes with a control systems toolbox, a toolbox that provides a way for systematically analyzing, designing, and tuning linear control systems.Simulink® is also a Mathworks product. It provides an interactive graphical environment and a customizable set of block libraries that let you design, simulate, implement, and test a variety of time-varying systems.The Program CC is a Systems Technology product. It provides a control system design package containing many tools and algorithms of current control system theory and practice.SIMAPP is another computer simulation software for modeling systems in the time and Frequency domains. The model is built visually through block diagrams.SCILAB is an open-source software similar to MATLAB. It comes with toolboxes appropriate for the simulation, design, and optimization of control systems. Moreover, as an alternative to Simulink, the Scilab team has developed an interactive graphical environment called XCOS.

Among the various methods for solving the Fourier heat conduction equation to obtain the thermal diffusivity, Laplace Transform is one (Carslaw and Jaeger 1959). This method uses the Laplace domain to solve the problem. In the end, the inverse Laplace Transform is applied to return to the time domain. Different methods (Galdino 1995) can solve the inverse Laplace Transform: searching a table of inverse Laplace transforms; decomposing inverse Laplace Transform into simple forms whose inverses are in a table; integrating the definition of the inverse Laplace transform analytically (Rice and Duong 1995; Grigoletto and Oliveira 2018), and solving the definition of the inverse Laplace transform numerically (Piessens and Dang 1976; Cohen 2007). Among the numerical methods for inverse Laplace Transform, it is possible to mention Talbot’s method (Talbot 1979; Cohen2007). Talbot’s method can be solved in computational form, as Murli and Rizzardi (1990) presented for Fortran, a difficult language, or in licensed software such as MatLab. A good alternative to Fortran and MatLab is Scilab (SCILAB 2021), free and open-source software with a simple language similar to MatLab. Scilab supplies a good computation environment to scientific applications with several numerical tools.

SVM is a classification method developed by Vapnik and Cortes [20]. One of the most relevant contributions was made by C. Chang and C. Lin: the LIBSVM project, a multilingual library with the main SVM algorithms. This library has become one of the most used and winner of the challenges like the Causation and Prediction challenge in 2008 and the Active Learning Challenge (2nd place) in 2010 [21]. LIBSVM contains algorithms for classification, regression and one class SVM. LIBSVM can be used with C++, Java and Python languages. Also, Scilab, Octave and MATLAB frameworks are supported.
