概要
- 論文の詳細を見る
The notch filter is usually used to suppress mechanical resonance of an actuator. However, the resonance frequency can vary due to manufacturing tolerance and environmental factors like temperature. In this paper, we present an adaptive digital notch filter that identifies the resonance frequency of the actuator precisely and adjusts automatically its center frequency. For the identification of resonance frequency, we propose a new estimation filter and its tuning algorithm. In order to demonstrate the practical use of our work, we present some experimental results for a commercially available disk drive.
