    Abstract
    This paper presents a unique dual-sensor signal fusion technology for DSP (digital signal processor)-based wide range vibration detection and active vibration control (AVC), which aims to suppress wide range vibration disturbances up to sub-micron level. In this method, two accelerometer sensors with different measurement ranges and sensitivities are used to detect the vibration disturbances as coarse and fine sensors respectively, and feed the signals simultaneously to a DSP controller. Each sensor is responsible for detecting accelerations in a specific range. By proper incorporation of signals from the two sensors, it is ...

    This paper presents a unique dual-sensor signal fusion technology for DSP (digital signal processor)-based wide range vibration detection and active vibration control (AVC), which aims to suppress wide range vibration disturbances up to sub-micron level. In this method, two accelerometer sensors with different measurement ranges and sensitivities are used to detect the vibration disturbances as coarse and fine sensors respectively, and feed the signals simultaneously to a DSP controller. Each sensor is responsible for detecting accelerations in a specific range. By proper incorporation of signals from the two sensors, it is possible to achieve a wide detection range of vibrations at low cost. Simulation study shows that in an AVC system with the proposed dual-sensor signal fusion approach as the vibration detection component, significant improvement can be achieved comparing with traditional single-sensor AVC systems.
