Reproduction of transport-induced vibration of paintings based on a multi-channel FxLMS controller

Abstract Monitoring the vibration of painting canvas during transport is great significance to protect paintings from damage. However, limited narrow structure crate, lack an inertial reference, and limitations attach sensors canvas, this a difficult task. For reason, based on data measured strainer that easily obtained transport, contribution proposes reproduce these with high accuracy in laboratory. There, resulting can be conveniently observed controlled environment respect reference. A real-time simulation platform multi-channel Filtered- x Least Mean Square (FxLMS) algorithm controls four actuators simultaneously reproduces real experiment. The then by laser Doppler vibrometer without contact. experimental results show reproduction system has sufficient for response. Even though some overshoot reproduced acceleration cases, overall very good. long-term experiment verifies its stable reproducibility. Therefore, designed provides reference unknown response further helps art conservators evaluate process painting.
