The vibration and radiation noise caused by the mechanical power equipment running on the ship have great harm, and seriously reduce the stealth performance and combat ability of the ship. The feedforward control algorithm which depends on the precise model will fail due to the adverse factors such as the long running of the power plant without stopping or the external impact. The traditional method of on-line system identification using auxiliary white noise not only reduces the control performance, but also increases the convergence time of the identification process. The method proposed in this paper uses the control signal to model the controlled system required by the FxLMS algorithm online in the noise frequency band, with faster convergence speed and identification accuracy. When the controlled system changes abruptly, that is, when the phase frequency characteristics of the controlled system change beyond ±90°, the algorithm can also track the changes of the system in real time and maintain the stability of the control. The active vibration control of the single-layer power unit vibration isolation platform was studied. The experimental results showed that the online identification of FxLMS control algorithm achieved 20.44 dB noise reduction at the motor operating frequency (50 Hz) when there was no secondary path model. The on-line identification algorithm can also maintain the control stability and quickly identify the changes in the phase frequency characteristics of the system after the mutation of secondary path.

舰船上机械动力设备运行产生的振动及其引起的辐射噪声有着很大的危害,严重影响了舰船的隐身性能和作战能力。由于动力装置长时间不停机的运转或外界的冲击等不利因素,会导致依赖于精确模型的前馈控制算法失效。传统利用辅助白噪声完成在线系统辨识的方法不仅降低了控制性能,同时也增加了辨识过程的收敛时间。本文利用含有噪声频段的控制信号对FxLMS算法的次级通道进行在线建模,有着更快的收敛速度和辨识精度。被控系统发生突变即被控系统相频特性变化超过±90°时,该算法也能实时跟踪到系统的变化并保持控制的稳定。针对所搭建的单层动力装置隔振平台进行振动主动控制研究,试验结果表明,在无次级通道模型时,在线辨识FxLMS控制算法实现了电机工作频率(50 Hz)处20.44 dB的降噪效果,次级通道发生突变后,在线辨识算法也能保持控制稳定,并快速识别突变后的系统在相频特性上的变化。
