EDUCATION OBJECTIVE

The course provides the methodological and technological expertise to develop electromechanical and electric systems for the industry automation. Two basic systems are considered: 1) industrial motion systems and 2) electric power conditioning systems. Three major subjects are covered: 1) modeling of the systems, 2) control of the systems and 3) usage of the microprocessor to implement the control and the networking of the systems.

LECTURE PLAN

• Apparatuses and devices for the industrial motion: electric drives (modeling, services, sizing, power rate) and sensors (accelerometers, tachometers, encoders)
• Mechanical systems (modeling, electromechanical analogies and their application)
• Industrial motion systems (analysis and design of schemes for controlling current, torque, acceleration, speed and position; scheme simulation by Matlab/Simulink)
• Apparatuses and devices for the electric power conditioning: dc-ac converters (modeling, control) and sensors (current and voltage sensors)
• Instantaneous power theory (power definitions, p-q power equations for sinusoidal, distorted and unbalanced three-phase systems)
• Electric power conditioning systems (grid distortion, grid synchronization, active power exchange, distortion compensation)
• Microprocessor control systems (structure, operation, modeling); outline on the digital control (discretization techniques, z-transform)
• Industrial communication networks (digital communication techniques, ISO/OSI model, physical and data link layers, CAN protocol)

ORGANIZATION

The lectures, including exercises, are given at the first semester along 12 weeks and are organized in blocks of 2 hours, with 6 hours per week. Total hours are 72. The course has 9 CFU credits.
