| Abstract: | Based on DSP local dynamic balancing system,the local dynamic balancing of the rotors with different rotate speeds can be tested accurately by adopting 32 multi-frequency and 50-frequency PLL.The realization of hardware synchronization full cycle sampling was introduced by using rotate speed benchmark signal 32 multi-frequency PLL as touching fountain for A/D.The realization of pick-up imbalance signal in local complex interfere was introduced by adopting central frequency self-adapting band-pass filter and... |
