Abstract:

A dry tuned two axis gyro having a pulse-rebalanced rate capture loop control. This configuration eliminates the need for an analogue-to-digital converter since the gyro is torquered at a pulse rate using a constant current source. Another feature of the control loop is a cross-channel shaping network which exchanges an electronically damped error from one axis to the other axis. By means of a summing network which combines the error signals from the main channel and the cross channel with a source of time varying ramp voltage, an alternately negative to positive signal is applied to the gyro torquer.
