Study Notes
Motor Control Systems
-
Types of Motor Control:
- Open-loop control: no feedback from the motor
- Closed-loop control: feedback from the motor to adjust control
-
Motor Control Techniques:
- PWM (Pulse Width Modulation): varies voltage to control motor speed
- FOC (Field-Oriented Control): controls motor torque and flux
- DTC (Direct Torque Control): directly controls motor torque and flux
-
Motor Control Applications:
- Industrial automation
- Robotics
- Electric vehicles
