Method of loop-shaping weighting functions for multi-axis vibration test control

JIANG Shuang-yan1,CHEN Huai-hai2,HE Xu-dong2,CUI Xu-li2 (1.MOE Key Lab of Structure Mechanics and Control for Aircraft,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China; 2.Institute of Vibration Engineering Research,Nanjing University of Aeronautic and Astronautics,Nanjing 210016,China )  
H∞ loop-shaping control method was proposed in the MEMA(multi exciter/multi axis) random vibration test.In practice,the response spectrums of the control points are always difficult to meet the reference ones at the frequencies where the frequency response function matrices are ill-conditioned.An H∞ pre-compensator was decomposed and designd for the controller.The conditions of the frequecy response fucntion matrices were thus improved and the controlled system was decoupled by using an algorithm.The Fourier spectrum of the driving signal was shaped by the compensator in the control loop to replace the original one.The experiment shows that with the present method,the driving singal is mended,the response spectrums of the control points are improved because of that the poor conditions of the frequency response function at specified frequencies are rejected.
