Objectives

The main goals of the discipline should reflect the skills to be acquired by the students:
• Specify a closed loop electromechanical driving system, with one or more axes, DC or AC motor based;
• Discuss and evaluate structures, control methods and selection criteria of the systems studied in the discipline;
• Work with modern electrical machines and control platforms;
• Develop simulation models for electrical drives;
• Design electrical drives;
• Work in team;
• Produce technical reports and make oral presentations.

Program

Introduction to electrical drives and systems.
DC motor based drives: electronic power converters and control methods.
AC motor based drives, asynchronous and synchronous: electronic power converters and scalar control methods. Vector control methods. Control of PM and brushless motors.
Electrical drive systems: position (linear and angular), speed and acceleration control. Control of two or more axes and multimotor drive systems.
Introduction to robotics.

Teaching methods and learning activities

The theoretical classes are tutorials with discussion of applied examples. The practical classes are of three types: home work discussing; accompanying the execution of the simulation and experimental works, and demonstration of industrial equipment.

Software

Matlab 6 R12.1
PSIM Network

Eligibility for exams

Not exceed the legal limit of faults and obtain a minimum of 40% in the practical work.

Calculation formula of final grade

The Final Classification is based on four components:
1. Resolution of two problems (PR)
2. Practical work (PW), simulation or experimental based
3. Oral presentation (OP) of the practical work
4. Final exam (EX), without notes, with a duration of 2 hours
The Final Classification is given by:
FC=0.15*PR+0.3*PW+0.05*OP+0.5*EX
Course approval is conditioned by a minimum of 40% in the practical work evaluation.

Examinations or Special Assignments

None.

Special assessment (TE, DA, ...)

None.

Classification improvement

The final exam component can be increased in the appropriate dates.

Observations

Pre-requisites: fundamental knowledge of electrical machines, power electronics and control systems.
