Specific educational targets

The aim of the course is to provide skilles and competences about typical informatics methodologies and technologies involved in industrial processes amnagement. At the end of the course, the student should be able to deal with the computer interfacing with different control systems, to acquire data coming from sesors, to dirve usual industrial actuators and to implement simple digital filtering on the acquired signals.

Moreover, throughout the course and in a specific section, the student will be introduced to embedded systems with an overview of typical computer architectures employed in this field.

Course program
