Theoretical and methodological lessons will be delivered together with example developments by face-to-face instruction in the classroom. Computer laboratory activities are aimed at developing the student’s skill through proper training. Each student is supposed to practice individually with the aid of laboratory work stations. The primary purpose of the laboratory exercises is to apply the methodologies presented in class, through the use of MatLab and Simulink. During the last week of the course, an exam simulation in the laboratory will be offered.

Modalità di esame: Prova scritta tramite l'utilizzo di vLAIB e piattaforma di ateneo Exam integrata con strumenti di proctoring (Respondus). ;
Written test using the vLAIB and Exam platform integrated with the proctoring tool Respondus, lasting 2 hours and divided into two parts. Part I. 4 or 5 multiple choice problems. For each problem, 4 possible answers are shown, only one of which is correct. Each problem has a different score based on its difficulty. The maximum score of this part is 17/30. Every exact answer leads to the full score, for every wrong answer a penalty corresponding to the 25% of the ful score is subtracted, every missing answer leads to null score. The goal of this first part of the exam is to verify the understanding of the fundamental theoretical topics of analysis and design of feedback control systems. Part II. 1 control design problem (maximum score: 17/30). The goal of this part of the exam is to verify the student skilness in designing a digital feedback control system through the loopshaping approach. Evidence of the design procedure must be provided in the terms of the matlab files developed for the design and a text document that reports the main steps of the design. The final grade is the sum of the scores achieved in the two parts. A mark of 30L/30 is given if the final score is greater or equal than 33. During the exam it is allowed to use a formulary provided by the instructor. Detailed instructions and rules will be presented during the course.
