Title:
CONTROL DEVICE FOR SWITCHED RELUCTANCE MOTOR
Document Type and Number:
Japanese Patent JP2016226084
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a switched reluctance motor, capable of suppressing a torque ripple even under a condition driven in high-current and high revolution.SOLUTION: A current sensor 10 detects a current flowing each phase of stator windings 9 of an SRM 8 through an inverter circuit 3, a multiplier 22 converts a rotor rotation position detected by a rotor position detector 13 into an electric angle. A hysteresis comparator part 25, provided for each phase, accepts a current command value which changes according to an electric angle at one of input terminals, and accepts a current sensor value of the current sensor 10 at the other of the input terminals, and outputs a comparison result of both values as an SW signal. An SW signal arbitration part 26 selects either the SW signal or a forced SWOFF signal which is outputted by an electric angle synchronous SW signal generation part 24, and outputs the selected signal to the inverter circuit 3 as a final SW signal.SELECTED DRAWING: Figure 1
