Embodiment
[0215] Using the finite time dissipation filtering method of a networked system under multipath fading channel proposed by the present invention, the external disturbance d(k)∈l 2 [0, N], the filtering error system is random and bounded within a finite time and has a certain anti-interference ability. The specific implementation method is as follows:
[0216] Consider the networked system model model and the multipath fading channel measurement model. The specific model parameters are:
[0217]
[0218]
[0219] Assume that the probability of random parameter uncertainty in the system is And the uncertain parameter matrix is:
[0220] M a =[1 0.7] T N a =[0.09 0.1]
[0221] Assume that the order of the attenuation model in equation (2) is L=2. Mathematical expectation of attenuation coefficient They are 0.8991, 0.3174, 0.5 and the corresponding variances are Mw=0.8, d 2 (k) = 0.2e -0.3k sin(k).
[0222] Given a finite time parameter as c 1 = 1, c 2 =50, Γ=1, N=20, δ=1.6, R=diag{...
