Title:
SWITCHED RELUCTANCE MOTOR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2019047573
Kind Code:
A
Abstract:
To reduce vibration and noise while suppressing deterioration of efficiency during regeneration of a switched reluctance motor.SOLUTION: In the switched reluctance motor control apparatus, a negative voltage to be applied in a regeneration region is calculated on the basis of an expression (1) (step S2), an excitation end angle at which application of the negative voltage in the regeneration region is started and a maximum current value which is the current value at the excitation end angle are determined on the basis of a rotational speed and a torque (step S8), a magnetic flux to be generated by a switched reluctance motor is estimated on the basis of the excitation end angle and the maximum current value (step S9), and an excitation start angle at which application of positive voltage in the regeneration region is started is determined by use of the estimated magnetic flux (step S11).SELECTED DRAWING: Figure 5
