Method for controlling brushless motor, device for controlling brushless motor, and elec tric power steering device |
| abstract |
A control device 50 that drives and controls a brushless motor 3 of a four-pole 24-slot configuration includes: a base current calculation section 52 that calculates fundamental-wave current indicating a winding current value associated with maximum torque control; a correction component calculation section 59 that calculates 12 th -order first higher harmonic wave component Bsin12(¸+²) to cancel a torque ripple of magnet torque, and 12 th -order second higher harmonic wave component Asin12(¸+±) to cancel a torque ripple of reluctance torque, based on a phase current value detected by a current sensor 64; a correction map 58 in which relation between phase current and parameters A, B, ±, and ² of the both higher harmonic wave components is stored; and a current correction section 60 that corrects supply current by superimposing each 12 th -order higher harmonic wave component on the fundamental-wave current in order to create current command values Id' and Iq'. |
