Hello, I am an electrical engineer having an extensive experience as a professor in higher education in engineering science and electrical engineering, as well as great experience as an embedded systems engineer, in EE architecture, ADAS, Testing and validations in the automotive sector.

I offer support courses and training in engineering science subjects, particularly in Automation and Industrial Control, to graduate students. My methodology is based on the acquisition of knowledge and course concepts in a very simple manner and also on practical experience using the most widely used software on the market.

Automation is the discipline that, generally speaking, deals with the control of systems. It is therefore very important in the industrial field, to which it provides solutions, study methods, and systematic analysis approaches. It is a scientific discipline that studies dynamic systems, signals, and information for the purposes of control or decision-making.

This course consists of six chapters, divided as follows:

Chapter 1: Introduction to Automation & Controlled Systems
Chapter 2: Mathematical Modeling of Controlled Systems
Chapter 3: Time & Frequency Analysis of Controlled Systems
Chapter 4: Controlling Systems & Block Diagram Algebra
Chapter 5: Stability & Performance of Controlled Systems
Chapter 6: Correction and Regulation of Controlled Systems
