为消除或抑制干扰噪声等非线性因素对多轴液压振动试验系统的影响,研究了自适应逆控制算法及其在振动控制领域的应用,提出基于频域X-滤波LMS自适应逆控制的多轴液压振动试验系统功率谱复现控制算法,给出了功率谱复现控制流程,并选用了一套双台并激液压振动试验系统作为具体试验对象进行试验验证,结果表明:所设计的控制算法及策略对双台并激振动试验系统具有较好的实际控制效果,满足工程试验要求。
In order to eliminate or suppress the influence of nonlinear factors such as interference noise on the multi-axis hydraulic vibration test system, the adaptive inverse control algorithm and its application in the field of vibration control are studied. Multi-dimensional LMS adaptive inverse control based on frequency domain X-filtering Shaft hydraulic vibration test system power spectrum recurrence control algorithm, gives the power spectrum recurrence control flow, and selects a set of double and parallel hydraulic pressure vibration test system as a specific test object to verify the test results show that: the design of the control The algorithm and strategy have good practical control effect on the dual-stage and excited vibration test system and meet the engineering test requirements.
