摘要： In a control apparatus of an electric power steering apparatus structured such as to control a motor applying a steering assist force to a steering mechanism on the basis of a current command value calculated from a steering assist command value calculated on the basis of a steering torque generated in a steering shaft and a current value of the motor, it is always possible to execute a high-performance control regardless of a steering speed, by setting a first differential compensator and a second differential compensator inputting a steering torque, making a sampling cycle of the second differential compensator slower than a sampling cycle of the first differential compensator, and adding outputs of the first differential compensator and the second differential compensator to the steering assist command value.

摘要： In a motor driving device where a motor having a winding wire with small inductance value is driven by a digital control means comprised of control means including a current command value calculating means, a current control means and a PWM control means whose sampling periods are different from each other, when discrete signals sampled by the respective control means are zero-order-held, a motor current includes a lot of higher harmonic waves due to a quantization error, thereby increasing a motor noise. When an n-th-order hold means is provided between the respective control means with different sampling periods, the quantization error can be reduced remarkably, and thus the higher harmonic wave components included in the motor current are reduced, thereby greatly reducing the motor noise.

The abnormality determining unit computes the absolute value of difference between the motor current estimate value and the detected motor current value, measures the number of times when the absolute value of difference exceeded the predetermined threshold value within the predetermined period, and measures further the cumulative value of the number of times of exceeding the threshold value within the predetermined period.
