Abstract:
PROBLEM TO BE SOLVED: To provide a moving element operating device which reduces movement caused by an offset when P control is switched to PID control. SOLUTION: A yaw axis operation signal E p is added to a control signal outputted from a P/PID controller 6, and the result is inputted to an actuator 9 so that yaw axis control is performed by a yaw axis drive part 10. A yaw axis angular velocity sensor signal S a is compared with a reference signal (r) and applied to the P/PID controller 6. A reference value memory 2 holds a yaw axis operation signal E p just before P control has been switched to PID control by a P/PID switch part 3, and uses the signal E p as a reference signal r b for use in performing the PID control. The reference value r b is added to an angular velocity zero detection reference value r z and the yaw axis operation signal E p and the result is outputted to the PID terminal of the P/PID switch part 3 so that the difference between the reference value r b and the yaw axis angular velocity sensor output S a is outputted to the P/PID controller 6.

Abstract:
PROBLEM TO BE SOLVED: To provide a gyro for a remotely controlled helicopter, improved in control characteristics against disturbance such as winds and in the response characteristic of yaw axis control during collect pitch control. SOLUTION: An angular velocity detection signal from a yaw axis angular velocity sensor 10 is added to a yaw axis operation signal from an operating unit and an angular velocity reference value, and the result is inputted to a PID controller 2.; The control signal of the PID controller 2 is added to a collect pitch operation signal and a yaw axis operation signal which come via a collect pitch → yaw axis control mixing device 3, and the result is inputted to an actuator 6 to control a yaw axis drive part 7. The angular velocity of a machine 9 around the yaw axis is detected by a yaw axis angular velocity sensor 10. COPYRIGHT: (C)1999,JPO
