Objectives
THE COURSE AIMS AT TREATING DIGITAL CONTROL APPLICATIONS TO PHOTOVOLTAIC SYSTEMS AND WIRELESS POWER TRANSFER SYSTEMS, WITH PARTICULAR FOCUS ON THE IMPLEMENTATION OF CONTROL ALGORITHMS FOR MAXIMIZING PRODUCTION AND MAXIMIZING ENERGY TRANSFER THROUGH THE USE OF EMBEDDED SYSTEMS

THE MAIN KNOWLEDGE ACQUISITIONS WILL BE:
• ENERGY, POWER AND EFFICIENCY IN PHOTOVOLTAIC SYSTEMS AND WIRELESS POWER TRANSFER SYSTEMS
• TYPES, OPERATING PRINCIPLE AND STATIC AND DYNAMIC MODELS OF DC-DC CONVERTERS FOR PHOTOVOLTAIC AND WIRELESS POWER TRANSFER APPLICATIONS
• CONTROL TECHNIQUES OF PHOTOVOLTAIC AND WIRELESS POWER SYSTEMS WITH FIXED CURRENT, FIXED VOLTAGE, FIXED POWER, MAXIMUM POWER AND MAXIMUM EFFICIENCY
• ARCHITECTURE, OPERATING PRINCIPLE, FEATURES AND SETTING OF DIGITAL CONTROL SYSTEMS FOR PHOTOVOLTAIC AND WIRELESS POWER APPLICATIONS;
• C LANGUAGE ENCODING, SIMULATION IN PSIM / MATLAB / SIMULINK AND VERIFICATION OF THE PERFORMANCE OF THE DIGITAL CONTROLLER OF A DC-DC CONTROLLER.

THE MAIN SKILLS TO APPLY THE ACQUIRED KNOWLEDGE WILL BE:
• ANALYZE THE BEHAVIOR OF PHOTOVOLTAIC AND WIRELESS POWER SYSTEMS WITH DIGITAL CONTROL UNDER STATIC AND DYNAMIC CONDITIONS;
• IDENTIFY PROJECT CONSTRAINTS THAT DETERMINE THE DESIGN SETTING OF A DIGITAL CONTROLLER FOR PHOTOVOLTAIC AND WIRELESS POWER SYSTEMS;
• EVALUATE THE DIGITAL CONTROL CONFIGURATION AND ITS APPROPRIATE PARAMETER SETTING FOR A GIVEN APPLICATION;
• USE CALCULATION AND SIMULATION PROGRAMS FOR THE ANALYSIS AND DESIGN OF PHOTOVOLTAIC AND WIRELESS DIGITAL CIRCUITRY CIRCUITS.
Prerequisites

FOR THE SUCCESSFUL ACHIEVEMENT OF THE GOALS, KNOWLEDGE OF MATHEMATICS, PHYSICS, CIRCUIT THEORY, AUTOMATION FUNDAMENTALS, COMPUTER PROGRAMMING BASICS IS REQUIRED

Teaching Methods

TEACHING INCLUDES 16 HOURS OF THEORETICAL LESSONS, 32 HOURS OF PRACTICAL EXERCISES IN THE LAB. THE EXERCISES DISCUSSES APPLICATION EXAMPLES OF MODELS, METHODS AND ALGORITHMS THAT ARE PART OF THE THEORETICAL LESSONS, AND STUDENTS ARE GIVEN CASE STUDY APPLICATIONS TO BE SOLVED BY DEVELOPING SYSTEMS AND CONTROL ALGORITHMS FOR PHOTOVOLTAIC SYSTEMS AND WIRELESS POWER OBJECT OF THE COURSE, DISCUSSING RESULTS IN COLLECTIVE FORM.
Verification of learning
THE EXAM IS INTENDED TO EVALUATE COMPREHENSIVELY THE KNOWLEDGE AND UNDERSTANDING OF THE CONCEPTS PRESENTED IN THE COURSE, THE ABILITY TO APPLY SUCH KNOWLEDGE TO SOLVE DIGITAL CONTROL PROBLEMS OF PHOTOVOLTAIC AND WIRELESS POWER SYSTEMS, THE AUTONOMY OF JUDGMENT, COMMUNICATION SKILLS AND THE ABILITY TO LEARN. THE EXAM CONSISTS OF AN ORAL COLLOQUIUM. THE COLLOQUIUM IS AIMED AT DISCUSSING A DIGITAL CONTROLLER PROJECT PROBLEM FOR A PHOTOVOLTAIC OR WIRELESS POWER SYSTEM, WHICH THE STUDENT DRAWS DURING THE COURSE, BASED ON SPECIFIC ASSIGNMENTS. IN PARTICULAR, THE STUDENT WILL HAVE TO ANALYZE THE STATIC AND DYNAMIC CHARACTERISTICS OF THE SYSTEM TO BE CONTROLLED, BY MEANS OF THE RELATED MODELS DISCUSSED IN THE COURSE, TO CARRY OUT THE CONTROLLER PROJECT, TO DETERMINE THE CONTROL NUMERICAL LAW OR ALGORITHM NEEDED TO ENSURE THE ACHIEVEMENT OF THE PERFORMANCE REQUIRED IN THE SPECIFICATIONS (CONSTANT VOLTAGE, CONSTANT CURRENT, CONSTANT POWER, MAXIMUM POWER, MAXIMUM EFFICIENCY). IN THE DESIGN REPORT THE STUDENT SUMMARIZES THE FRAMING AND FORMALIZATION OF THE PROBLEM, THE RESULTS OBTAINED THROUGH THE DEVELOPED SOLUTION AND THEIR CRITICAL DISCUSSION. THE PURPOSE OF THE ORAL TEST IS THEREFORE TO EVALUATE THE ABILITY TO APPLY THE ACQUIRED KNOWLEDGE, THE ABILITY TO FORMALIZE THE PROBLEM AND ITS RESOLUTION, AND THE AUTONOMY OF JUDGMENT. THE COLLOQUIUM ALSO AIMS AT EVALUATING THE ABILITY TO PRESENT AND DISCUSS THE CONTENT OF THE DESIGN REPORT AND TO ARGUE THE CHOICES MADE ON THE BASIS OF THE TOPICS DISCUSSED DURING THE COURSE. THE EVALUATION OF THE REPORT TAKES INTO ACCOUNT THE KNOWLEDGE OF THE STUDENT AND THE LEVEL OF INSIGHT, THE DEMONSTRATED LEARNING ABILITY, THE QUALITY OF THE PRESENTATION AND THE QUALITY OF THE DISCUSSION. IN THE FINAL EVALUATION, EXPRESSED IN THE SCALE FROM 18 TO 30, WHERE 18 IS THE MINIMUM AND 30 IS THE MAXIMUM. THE EXAM IS PASSED IF THE SCORE ACHIEVED IS AT LEAST 18. THE EVALUATION OF THE ORAL DISCUSSION AND OF THE DESIGN REPORT WILL WEIGH EACH 50%. HONORS MAY BE ATTRIBUTED TO STUDENTS WHO DEMONSTRATE THAT THEY KNOW HOW TO APPLY THE ACQUIRED KNOWLEDGE WITH CONSIDERABLE AUTONOMY AND CRITICAL MEANING.
