Abstract

PURPOSE:To avoid or reduce a cross-coupling effect, by providing rotation-inertia compensating part, which has a rotor that is rotated in the reverse direction with respect to the rotor of a rate gyroscope. CONSTITUTION:A rate gyroscope is constituted of a main body 20 of the rate gyroscope, which has a rotor provided with rotation inertia in the rotating direction OMEGA, and which detects the rotary angular speed in space; and a rotation- inertial compensating part 21, which has a rotor having the rotation inertia equivalent to reverse direction PHI. When torque is applied to a space rotary axis alpha o theta, precession action, which is turned around the other axis, is cancelled. The rotary force can be generated only around the axis, to which the torque is applied. Therefore, when the gyroscope is used in a space stabilizing device (used in a tracking device or in an attitude stabilizing device in a missile), a coupling effect is not generated. By utilizing two rotors, which are rotated in the reverse directions, an antenna system, which can perform rosette scanning can be readily constituted.

The conventional rate gyro used here has an internal rotor with rotational inertia in the direction Ω shown in the figure,
The amount of rotor preset when the spatial rotation angular velocity is input? It has a structure for detection. The rotational inertia of the rotor inside this V-gyro also produces a gyroscopic effect when the L-gimbal is rotationally driven by the inner gimbal torque motor 12'E or the outer gimbal torque motor 14. When the outer gimbal 3 is driven around the σ axis 9 with /PAL torque%-/14, the inner gimbal 11 is rotationally driven around the inner gimbal axis α by preset. This effect is usually called cross-coupling, and it complicates the circuits that make up the entire control system.At the same time, the torque motor's driving capability is not only the torque that drives the gimbal rotation, but also the preset cancellation when driving other axes. Since this rotor needs to have a large torque, the p1 device configuration must become large.
