Conoscenze e abilità da conseguire

The objective of the course is to introduce advanced mathematical tools that are instrumental in many fields of automation engineering. Specific topics that are presented in the course regard fundamentals in probability theory, combinatorial calculus, random variables and calculus, stochastic processes, elements of statistics. Besides theoretical tools the course will introduce SW packages for handling stochastic variables. At the end of course students masters key statistical tools that play a role in estimation, filtering and control.

Metodi didattici

Standard lectures in which the basic theory is explained will be combined with several examples and exercises

Modalità di verifica dell'apprendimento

Written test (2 hours) and oral examination.The written test is mainly focused on exercises for the solution of which the student is expected to apply the theory learned during the course. If the evaluation of the written test is satisfactory, the student has access to the oral examination. The validity of the written test is limited to the same session of exams. The oral examination is aimed at verifying the knowledge gained by the student concerning mainly the theoretical part of class. The final mark takes into account the evaluations of both the written and the oral part of the exam.
