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,is added to the yaw-axis control signal and the angular velocity reference value from the controlling gear. The PID controller,receives the resultant addition signal. The control signal from the PID controller,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,. The actuator,receives the resultant addition signal and controls the yaw-axis driving unit,. The yaw-axis angular velocity detection sensor,detects the angular velocity around the yaw-axis of the airframe
