| Summary |
|---|
| The subject develops basic knowledge of controlled electrical drives. It deals with better knowledge of modern methods of controlled electrical drives with synchronous motor, induction motor and with switching reluctance motor. There is also shown applications of artificial neural networks and fuzzy logic in control of electric drives. |
