A　self-tuning　vibration　absorber　is　capable　of　adjusting　its　intrinsic　frequency　in　real　time　to　track　the　excitation　frequency　and　achieve　effective　vibration　control　over　a　wide　frequency　range.　In　this　study,　a　self-tuning　vibration　absorber　control　system　based　on　STM32　is　proposed.　The　system　acquires　vibration　signals　using　MPU6050　sensors,　calculates　the　vibration　frequency　in　real　time,　and　controls　the　motor　rotation　to　achieve　self-tuning　vibration　absorber　control.　The　system　employs　the　STM32F407ZGT6　as　the　core　control　chip　and　is　designed　in　terms　of　the　overall　scheme,　hardware　circuit,　and　software.　For　hardware,　the　system　uses　the　STM32F407　as　the　control　core　and　the　MPU6050　sensor　to　obtain　vibration　signals　while　controlling　motor　rotation　using　the　TMC2209　motor　driver　chip.　Keil　μVision　software　is　applied　for　program　writing　and　debugging.　The　system　mainly　includes　modules　for　data　acquisition,　signal　processing,　control　algorithm,　and　drive　output.　The　signal　processing　module　employs　the　fast　Fourier　transform　(FFT)　algorithm,　which　can　achieve　fast　frequency　calculation　and　vibration　frequency　tracking.　Finally,　experiments　verify　the　system＇s　feasibility　and　effectiveness.　The　experimental　results　demonstrate　that　the　system　can　accurately　control　the　self-tuning　vibration　absorber,　with　excellent　control　performance　and　practicality.　©　2024　Institute　of　Physics　Publishing.　All　rights　reserved.
