最適制御を用いた相対加速度信号に導入によるアクティブ地震計の性能向上

Key Points

• The central aim is to improve the performance of active seismometers by enabling better measurement of seismic waves.
• Utilized a sensor with internal weights, springs, dampers, and actuators.
• Applied control to enhance the vibration of internal weights for accurate measurement.
• Targeted detection of seismic movements with a period of 10 seconds and amplitude of 1 meter.
• Successfully developed a seismometer capable of measuring slow vibration movements.
• Enabled reliable data acquisition for large amplitude seismic waves.
• Demonstrated effective control to allow proper internal weight movement during seismic events.
