ABSTRACT:
A drift canceling apparatus has an angular velocity detecting sensor with a detection output having temperature/time drift, the output being supplied to an object to be controlled. A reference signal extraction circuit extracts a reference signal from the detection output. The reference signal extraction circuit includes a differentiation circuit for differentiating the detection output of the angular velocity detecting sensor, a comparison circuit for comparing the detection output of the angular velocity detecting sensor with the output signal of the differentiation circuit to produce a comparison circuit output signal, a selection circuit for selecting only an output in a required normal operation region from the comparison circuit output signal, and a sample hold circuit for sample-holding the detection output of the angular velocity detecting sensor in response to the output of the selection circuit to produce a sample hold signal used as the reference signal. A control signal generation circuit is provided for generating a control signal from the output of the angular velocity detecting sensor on the basis of the reference signal.
