20810249 - CONTROLLI AUTOMATICI

The course will propose the basic concepts of Automation. It will be developed the ability of analysing simple dynamical systems (stationary and linear) with one input and one output. Along the course will be used representations based on continuous time and frequency with the use of Laplace Transform. Feedback systems will be analysed trying to point out main characteristics. Some techniques will be illustrated to design control loops respecting frequency and time constraints.
Then, it will be illustrated some structural properties of continuous time models and will be introduced concepts like coordinate transformation, modal anaysis, canonical forms, controllability and observability. The course will present control techniques using pole placement approaches, and observers. They will be carried out many practical lessons using MATLAB software that will be used also for designing control systems for the exam

Type of delivery of the course

The agenda of the course includes both traditional lectures and classroom exercises on problems of modeling, analysis and control of dynamic systems. The teaching material provided by the teacher includes exercises on the software Matlab. The exercises in Matlab are carried out in the classroom and sources are provided to students.

Attendance

Although not mandatory, attendance is strongly recommended in consideration of the strong link existing between the theoretical part of the subject matter and the applications.

Type of evaluation

Written, oral exam and exam during the course.
