Learning Objectives

The aim of the course is to describe the technological aspects for the realization of control systems. In particular, the main objective is to provide the student with some basic knowledge needed for the choice of components and architectures of a control system for applications in the field of industrial automation, robotics, domotics and automotive. The characteristics of the control loop will be discussed in relation with the physical processes to be controlled and with the temporal constraints deriving from them on the computational and communication tasks.

Knowledge and understanding

At the end of the course the student will acquire: knowledge of the theory and of the practical aspects of the control systems technologies; understanding of the physical principles underlying sensors and actuators; knowledge of the devices and their operation; knowledge of technologies for the design of a control system.

Applying knowledge and understanding

The course will allow to obtain ability to design and realize control systems, integrating the various technologies proposed with the aid of micro controllers or with specific software.

Making judgements

Development of autonomous judgment skills to evaluate which sensors and actuators, along with the control laws, are needed for the design of a control system.

Communication skills

Development of communication skills to represent both technological and thoretical aspects in the design of a control system including the controllers, the sensors and the actuators.

Learning skills

Be able to apply the acquired skills to the design of the technological aspects of a control systems.
