Goal of the subject is to provide students with basic knowledge on dynamic systems analysis and on simple control system design for linear time invariant continuous time systems described in terms of state variables and transfer function. Attention is mainly focused on general methodologies that allow to deal with dynamic systems whose dynamic equations are provided. In the first part of the course systems described in state variables are considered. For such systems stability controllability and observability properties are defined and analyzed. State feedback and state observer are introduced as well. In the second part of the course feedback control design for SISO systems with no poles in the right hand plane is considered.

Lectures and tutorials are not rigidly separated. Tutorial cover exercises on the developed theory as well as the development of more practical parts of the program. There is no division in groups for activities in class.
Part of the study will be conducted in the LAIB to have access to multimedia material available through the web and to conduct lab sessions. Lab tutorials should enable to get basic knowledge of a modern program (MATLAB) for analysis and design of control systems. With the aid of such program students can carry on exercises similar to those developed in class lectures and tutorials, but they can also work out more complex problems that could hardly be developed without the aid of a computer.
Lab tutorials will cover:
Study of the time response of dynamic systems,
Analysis of controllability and observability as well as state feedback.
Drawing of Bode and Nyquist plots for different transfer functions.
Comparison of open loop and closed loop transfer functions.
Design of feedback compensators.

- The exam consists in a 3-hour test conducted in the Lab with Matlab available.
- The exam consists of two exercises, one on the design of feedback compensators and the other on the analysis of dynamic systems described in state variable form.
- According to the rules the exam outcome is recorded even if a student withdraws. It is therefore not allowed to reject the grade. However the student can declare, at the time in which she/he hands over her/his exam book, which is the minimum grade she/he would like to have, so that, in case she/he does not reach that grade she/he will be considered as withdrawn.
During the exam it is not allowed do go out from the lab beside in the case in which one withdraws or has completed the test. Students that cannot stand with this regulation for medical reasons should contact the instructor in advance. Last minute requirements will not be considered.
- During the exam students can have on the desk only pencils, pens and drawing tools and white sheets. Any other material is banned (telephones, books, bags, cloths etc.) and should be deposited according to the instructions that will be given.
- During the exams it is not allowed to use any text book (or other book) notes etc., beside one A4 sheet on which the student can report any note she/he considers useful with the exception of exercises partly or totally solved and coded answers to specific exercises. The sheet should be hand written and not photocopied; it is strictly personal and should report name, surname and Identification number of the student. It is also allowed a second A4 sheet with the Laplace transforms and transformation rules as well as a third sheet with the universal plots and the Nichols charts.
- During the exam in the LAIB students are not allowed to bring in any calculator since they can use the PC in the lab.
- No material on electronic support (diskettes, USB keys, photos, etc.) is allowed in or out from the class/lab.
