Training objectives
- The course aims at introducing the student to the technology adopted in the implementation of control algorithms for dynamic systems, with particular regard to sensors and transducers, components for the conditioning and the acquisition of sensory information and physical architectures for digital control systems.
Knowledge and understandings:
- physical principles used for measuring engineering quantities (e.g. temperature, electrical current, displacement, velocity, acceleration, etc.)
- electronic components of sensors signal conditioning and acquisition chains
- general features of microprocessors adopted for the realization of digital control systems (microcontrollers and Digital Signal Processors/Controllers, DSP/DSC)
- basics of automation and control networks (i.e. fieldbus)
Such a knowledge can be applied by students to:
- select the most suitable technologies for the realization of a digital control system, including the selection of sensors/transducers, the tools for signals acquisition and digitalization and the devices executing control software
- program basic functions for the configuration of microcontrollers/DSPs/DSCs, related to sensors/transducers interfacing and their use in an automatic control application. Prerequisites
- Automatic Control Theory, Analog Electronics, Computer Science
Course programme
- Sensors and transducers: generalities, static and dynamic characteristics, physical principles; position sensors, velocity sensors, strain gauges, force and pressure sensors, temperature sensors, current sensors and digital proximity sensors. Acquisition of analog signals: conditioning, amplifiers, filters, isolation, multiplexers, sample and hold, analog-to-digital (A/D) and digital-to-analog (D/A) converters.Architectures of digitaSensors and transducers: generalities, static and dynamic characteristics, physical principles; position sensors, velocity sensors, strain gauges, force and pressure sensors, temperature sensors, current sensors and digital proximity sensors. Acquisition of analog signals: conditioning, amplifiers, filters, isolation, multiplexers, sample and hold, analog-to-digital (A/D) and digital-to-analog (D/A) converters.Architectures of digital control systems: embedded systems (Microcontrollors and DSP), general-purpose systems (Personal Computer, VMEBus, PLC), distributed systems (DCS and SCADA); digital networks for distributed control systems (CAN and Profibus).
Didactic methods
- The teaching activity is organized so that the required knowledge is acquired during lectures and practical sessions in a Electronics Laboratory.
Such practical sessions present the use of demonstration boards with a Digital Signal Controller and allowing the implementation of control schemes for small electrici motors. The laboratory has 9 demonstration boards and the students are required to organize in groups of up to three persons. Learning assessment procedures
- The exam can be taken with one of the following two alternatives:
1) WRITTEN EXAM, with multiple choice questions and one exercise related to Digital Signal Controller programming.
2) PROJECT + WRITTEN EXAM: the student AUTONOMOUSLY develops a simple digital control design project, preferably (not mandatorily) using a Digital Signal Controller board provided by the teacher. The project idea must be approved by the teacher before the student can start its development and the project realization must be shown with a working demonstration before the written exam.
After the project demonstation, the student can take the WRITTEN PART, with multiple choice questions on Sensors and Transducers shown during the course.
Passing the final exam is the proof that knowledge and abilities outlined in the training objectives of the course have been achieved. Reference texts
