• Abstract:

  Automatic Control Systems are far and wide used in all modern and industrialized societies. Devices designed to control automatized tasks are each time more present from small plants to large industrial buildings.

  The development of mathematical models is a compulsory task for whom aim at analyzing or design any control systems. These mathematical models must reproduce some performance measures as accurate as possible. So, no matter the physical nature of the process we aim at control, an accurate mathematical model must be evaluated. So, the development of mathematical models can be considered an hi-level step over the physical nature of the system that we aim at analyze or design. For this reason the study of Systems Theory and Control Systems are considered transversal areas of the knowledge and them studies are compulsory in many branches of sciences and technologies in many universities all over the world. In spite of normal systems are non-linear the linearization procedure simplify the analysis and design of control systems and, depending on the accuracy of the model can give us good results.
