Before machines were made, automatic conveyor systems were installed, and before every controlled systems were put into operation –they were first modeled. Modelling a system lessens the expenses required in doing a trial and error on a system by making an algorithm or putting the system into mathematical equations. It predicts possible outcomes of a certain input was processed into the system. In short, modelling helps engineers design a system suitable for operation without expending too much. And in order to facilitate this modelling, a powerful software must be used. It should have a capacity to simplify a solution to a complicated mathematical model. And of course, the software must be within our reach. And this, is where MATLAB and Simulink play their role. You could download your MATLAB program here, it is pre-installed already with Simulink Toolbox. So, download it now while I help you to get started with MATLAB and design your own control system.So stay tuned and let me help you to know your MATLAB.
