Objectives
THE COURSE AIMS TO PROVIDE THE STUDENTS WITH A SOUND METHODOLOGICAL BASE FOR UNDERSTANDING THE FUNCTIONAL CHARACTERISTICS OF THE MOST IMPORTANT ELECTRICAL DEVICES AND SYSTEMS, LIKE SENSORS, ACTUATORS AND ENERGY SOURCES, THAT INTERFACE WITH MICROCONTROLLERS IN EMBEDDED OR MODULAR SYSTEMS. THE COURSE ALLOWS THE STUDENTS TO ACQUIRE, BY MEANS OF LABORATORY ACTIVITIES, THE ABILITY TO MODEL THE SELECTED DEVICES AND TO IMPLEMENT CODES TO USE THEM IN SIMPLE CONTROL / ACTUATION SYSTEMS BASED ON MICROCONTROLLERS.

KNOWLEDGE AND UNDERSTANDING
TO KNOW THE WORKING PRINCIPLE OF THE MOST COMMON TYPES OF SENSORS, ACTUATORS AND SYSTEMS FOR THE STATIC AND ELECTROMECHANICAL ENERGY CONVERSION. TO KNOW THE MAIN CIRCUITS, METHODS AND ALGORITHMS FOR INTERFACING SENSORS AND ACTUATORS WITH THE EMBEDDED SYSTEMS THAT ARE MORE COMMONLY USED IN INDUSTRIAL APPLICATIONS.

APPLYING KNOWLEDGE AND UNDERSTANDING
TO CHOOSE THE PROPER SENSORS AND ACTUATORS FOR SOME INDUSTRIAL APPLICATIONS, TO KNOW HOW TO INTERFACE THEM WITH AN EMBEDDED SYSTEM AND TO DESIGN AND IMPLEMENT THE CONTROL ALGORITHM BY USING HIGH LEVEL PROGRAMMING TOOLS.
Prerequisites
PRELIMINARY KNOWLEDGE ON BASIC CIRCUIT THEORY AND AUTOMATIC CONTROLS IS USEFUL.

Teaching Methods
THE COURSE INCLUDES THEORETICAL LESSONS, SIMULATION EXERCISES AND A SIGNIFICANT PART OF EXERCISES ON HARDWARE IN LABORATORY. SIMULATIONS COMPLETE THE THEORETHICAL LESSONS AND THEY ARE AIMED AT ASSESSING THE KNOWLEDGE OF SENSORS AND TRANSDUCERS, AS WELL AS THEIR INTERFACING WITH EMEBDDED SYSTEMS. A FIRST PART OF THE EXPERIMENTAL TESTS IS DEDICATED TO THE ANALYSIS OF THE HARDWARE AND TO BASIC CASE-STUDIES. AFTERWARDS, STUDENTS WORK AUTONOMOUSLY, IN SMALL GROUPS, WITH THE SUPPORT OF THE TEACHER. THE LABORATORY EXERCISES MIGHT BE SUPPORTED BY EXPERTS COMING FROM INDUTRIES OR OTHER UNIVERSITIES, WHO MAY EVEN CONTRIBUTE TO THE KNOWLEDGE OF SPECIFIC TOPICS THROUGH SEMINARS.
Verification of learning
THE EXAM IS AIMED AT ASSESSING THE WHOLE KNOWLEDGE OF THE CANDIDATE: UNDERSTANDING OF WHAT EXPLAINED DURING THE LESSONS, APPLYING SOME GIVEN CONCEPTS TO NEW CASES INCLUDING AN EMBEDDED SYSTEM WHICH HAS TO BE INTERFACED WITH SENSORS AND ACTUATORS, THE CRITICAL EVALUATION OF THE RESULTS, THE ABILITY TO EXPLAIN CONCEPTS. THE CANDIDATE HAS TO EXPLAIN ORALLY THE RESULTS OF THE PRACTICAL ACTIVITY THAT HE/SHE DID IN LABORATORY ON THE PROJECT ASSIGNED TO HIM/HER.
