78758 - Control Systems Technologies M

Course Unit Page

Academic Year 2018/2019

Learning outcomes

At the end of the course students acquire the knowledge of structure and use of the main hw/sw tools for control systems in automation

Course contents

The main goal is to elaborate on the main engineering and technological issues related to the realization (at the industrial level) of modern control and automation systems.

Two main topics can be highlighted:

- Architecture/components of control systems and industrial automation;

- Software for control and automation.

The former theme deals with control systems HW architecture, mapping “functional schemes” (discussed in Fundation of Control Systems Courses) into “technological schemes”. Then, the classes of devices typically used in control systems realization. For each class, some components are analyzed, focusing on the criteria to choose and size them, based on the application.

For what concerns the second topic, the main aspects of implementing control algorithm into SW systems are discussed. Specifically, the problem of managing the different working phases of a system, via the standard IEC61131. Particoular effort is devoted to implementation into PLC (Programmable Logic Controller) which is a standard for automation. Using a specific CAD, several examples are presented, assigning then a project (related to an automation problem) to be autonomously carried out.
