Title:
モータ制御装置及び電動パワーステアリング装置
Document Type and Number:
Japanese Patent JP5772359
Kind Code:
B2
Abstract:
An ECU (11) that controls a motor (12) includes: a target current value setting unit (30) setting a target current (It); a voltage detecting unit (50) detecting a detected voltage (Vd) on the basis of a detection signal from a voltage sensor (23); a voltage calculation unit (51) calculating an estimated voltage (Ve) on the basis of a power supply voltage (Vps) of a battery (24); and an induced voltage observer (38) calculating an induced voltage (E) generated at the motor (12) using an inter-terminal voltage (Vt) based on the estimated voltage (Ve) when the target current (It) is set to a value other than zero; whereas the induced voltage observer (38) calculates the induced voltage (E) using an inter-terminal voltage (Vt) based on the detected voltage (Vd) when the target current (It) is set to zero.
