Abstract: A steering angle calculation circuit of an ECU includes a neutral point calculation circuit, a correction amount calculation circuit, an adder, and an absolute angle calculation circuit. When started, the neutral point calculation circuit calculates a motor neutral point from a steering angle detected through a steering sensor and a motor rotation angle detected through a relative angle sensor. The correction amount calculation circuit calculates a correction angle that is a difference between a conversion value and an actual value of the motor rotation angle with respect to the steering angle. The conversion value is obtained by converting the steering angle in terms of the motor rotation angle by taking into account a theoretical specific stroke. The adder calculates a final motor neutral point by adding the correction angle calculated by the correction amount calculation circuit to the motor neutral point calculated by the neutral point calculation circuit.

Abstract: A steering angle calculating circuit includes a first neutral point calculating circuit, a second neutral point calculating circuit, and an absolute angle calculating circuit. The first neutral point calculating circuit calculates a motor neutral point (?m01), based on a steering angle detected by a steering sensor and a rotation angle of a motor detected by the relative angle sensor, when a drive source for driving a vehicle is started. The second neutral point calculating circuit calculates a motor neutral point when the steering angle detected by the steering sensor falls within a predetermined angle range in which a specific stroke with respect to the steering angle is constant. After the motor neutral point is calculated by the second neutral point calculating circuit, the absolute angle calculating circuit calculates the steering angle as an absolute angle, using the motor neutral point calculated by the second neutral point calculating circuit.

Abstract: A nuclear reactor power regulator adjusts reactor output based on a reactor output target value and a reactor output change rate. The regulator includes a reactor output calculating device that performs computation based on a thermal equilibrium from power signals of plant parameters to calculate a reactor output signal. A correcting device corrects a continuously obtained reactor output equivalent signal that is considered to be equivalent to a reactor output at a calculation interval of the output signal, so that the output equivalent signal coincides with the output signal. The correcting device calculates a continuous corrected output equivalent signal. A reactor output controlling device calculates a reactor output control signal for controlling the output of the reactor, using the corrected reactor output equivalent signal, the reactor output target value, and the reactor output change rate. A reactor output controller is operated based on the reactor output control signal.
