摘　　要：针对一类同时具有外界干扰和范数有界的参数摄动时滞系统,研究了其鲁棒H∞滤波的问题,利用Lyapunov稳定性理论,基于线性矩阵不等式的方法,设计了鲁棒H∞滤波器。通过线性化磁悬浮系统运动方程模型,建立了磁悬浮系统的数学模型,得到了其状态空间方程,并将所设计的鲁棒H∞滤波器应用于磁悬浮系统位置的稳定控制,由实验可以看出,悬浮盘片可以很快的稳定到初始位置并保持基本的平衡状态,从而验证了所设计的鲁棒H∞滤波器的有效性。A class of parameters perturbed time-delay systems with external disturbances and norm bounded parameter was studied.The robust H∞ filter is designed based on Lyapunov stability theory and linear matrix inequality.The mathematical model of the magnetic levitation system is established by linearizing the equation of motion equation of the magnetic levitation system,and its state space equation is obtained.By establishing the model of the magnetic suspension system and applying the robust H∞ filter to the stability control of the magnetic levitation system＇s position,It can be seen from the experimental waveform that the suspended object can quickly stabilize to the initial position and maintain the basic equilibrium.The validity of the designed filter was verified.
