1. A driving controller comprising:
- a controller includinga signal value acquisition part that, every predetermined sampling time, receives a detection signal outputted from a sensor part in accordance with a rate of rotations or speed and acquires a signal value for the detection signal, andan actuator control part that controls the rate of rotations or speed at control timings with predetermined intervals using the signal value obtained by the signal value acquisition part, whereinin response to a plurality of signal values obtained before an outstanding control timing monotonically increasing or monotonically decreasing, the actuator control part controls the rate of rotations or speed using the most recent signal value before the outstanding control timing, andin response to the plurality of signal values obtained before the outstanding control timing not monotonically increasing or monotonically decreasing, the actuator control part controls the rate of rotations or speed using an average value of the plurality of signal values obtained before the outstanding control timing.

Abstract
In order to possibly suppress noise components contained in a signal value of a detection signal for use in controlling a rate of rotations or speed, an driving controller receives a detection signal in accordance with a rate of rotations or speed and acquires a signal value of the detection signal every predetermined sampling time, and controls an actuator at control timings with predetermined intervals using the signal value, so that the rate of rotations or speed is controlled at each of the control timings in accordance with variation aspects of a plurality of signal values acquired before the outstanding control timing.
