Abstract
A gyroscope suitable for a remote-controlled helicopter is provided that can improve the control characteristics to a disturbance factor such as wind as well as the response characteristics under yaw-axis control in a correct pitch operation. The angular velocity detection signal from the yaw-axis angular velocity sensor 10 is added to the yaw-axis control signal and the angular velocity reference value from the controlling gear. The PID controller 2 receives the resultant addition signal. The control signal from the PID controller 2 is added to the correct pitch control signal and the yaw-axis control signal sent via the correct pitch to yaw-axis control mixing unit 3. The actuator 6 receives the resultant addition signal and controls the yaw-axis driving unit 7. The yaw-axis angular velocity detection sensor 10 detects the angular velocity around the yaw-axis of the airframe 9.
