This course aims at giving to participants all the mathematical tools required in the analysis and design of control systems, together with the basics on technological aspects related to their realization. A classic mechatronic problem, i.e., the design of a motion control system, is used as a case study to show a realistic application of these tools.
The first part of the course deals with the basics on systems theory for continuous time and discrete time systems, and introduces the control system design problem, focusing on the tools required to analyze stability and performance of feedback control systems. Time domain and frequency domain design approaches are then introduced. The indirect digital controller design problem, i.e., the transformation of a continuous time control system into a digital one, closes this part.
The second part of the course presents an application of frequency and time domain control methodologies to a mechatronic problem, i.e., motion planning and control of a servomechanism, and introduces the basics on technological aspects related to the realization of control systems. In particular, hardware technologies, related to conditioning, filtering, analog-to-digital and digital-to-analog conversion, and software technologies, related to control system design, communication networks and Programmable Logic Controllers (PLCs), are discussed.
