【摘要】：针对参考信号频率与振源频率偏差造成往复海水泵自适应主动控制性能下降的问题,提出直接泄漏滤波X最小均方的自适应振动控制算法。通过一种几何关系来进行参考信号的相位更新,并基于泄露滤波X最小均方误差方法,设计了直接进行频率函数控制更新和控制权系数更新的振动控制算法。通过泄露因子限制控制输出能量。为验证该方法的有效性,进行了仿真。仿真结果表明,该方法能够通过自调节参考信号频率,跟踪振源信号变化,取得良好的振动抑制效果。进行了水泵试验台架的振动控制试验,检验该自适应控制算法性能。试验结果表明,该方法能够对频率缓慢变化的水泵振动进行有效的自适应振动控制。
[Abstract]:In order to solve the problem that the adaptive active control performance of reciprocating seawater pump decreases due to the deviation between the frequency of reference signal and the frequency of vibration source, an adaptive vibration control algorithm with direct leakage filter X minimum mean square is proposed. A geometric relation is used to update the phase of the reference signal, and based on the leakage filter X minimum mean square error method, a vibration control algorithm is designed to update the frequency function control and the control coefficient directly. The output energy is controlled by leakage factor limitation. In order to verify the effectiveness of the method, the simulation is carried out. The simulation results show that the method can track the change of vibration source signal by self-adjusting the frequency of reference signal, and achieve good vibration suppression effect. The vibration control test of the pump test bench is carried out, and the performance of the adaptive control algorithm is tested. The experimental results show that the method can effectively control the vibration of the pump with slow frequency change.
