PURPOSE:To obtain a motor controller employing a software serve system disturbance estimation observer requiring no hardware such as A/D converters or D/A converters. CONSTITUTION:Angular speed OMEGA of a motor is calculated based on an FG signal fed from the FG section 13 of the motor. A speed error signal Bn of the motor is then determined based on thus calculated angular speed OMEGA and added to an estimation value Cn fed from a disturbance estimation observer 7 and the sum An is fed to the disturbance estimation observer 7. Consequently, hardwares such as A/D converters or D/A converters not required, resulting in simplification of the constitution and enhancement of control performance. |
