Yawing by a closed loop control system What was yawing? Contents of the system – Direction sensor – Motor – Microcontroller & Circuitry

Yawing by a closed loop control system – Direction sensor

Yawing by a closed loop control system – Motor

Yawing by a closed loop control system – Microcontroller & Circuitry PIC 16F877

Blade pitch adjusment by a closed loop control system What was pitch adjustment? Contents of the system – Linear position sensor – Motor – Microcontroller

Blade pitch adjusment by a closed loop control system – Motor

Blade pitch adjusment by a closed loop control system – Linear position sensor

Sensors used in control system Three types of sensors: Angular direction sensor for yawing Linear position sensor for pitch adjustment Angular resolver for speed measuring

Sensors used in control system Angular direction sensor for yawing

Sensors used in control system Linear position sensor for pitch adjustment

Sensors used in control system Angular resolver for speed measuring

Motors to be used Step motor with high torque – High torque  High Current DC motor with a gear box – Needs additional device for feedback

Putting all together
