| 摘要 |
The invention relates to an electric motor controller capable of suppressing the vibrating of a control object and controlling the control object with high speed and high precision without a special sensor. The electric motor controller (1) comprises a speed detector (2), an encoder (3) forming a position detector, a speed controller (4), a position controller (5), a torque controller (6), and a peak value filter (7). The peak value filter (7) determines a transferring function via the following mode, namely, amplifying an anti-resonance frequency component in a machine base vibration generated between the machine base equipped with the electric motor and the control object, and forming the control object to be a rigid body system not containing the anti-resonance characteristic in the frequency of the anti-resonance frequency component. |
