Richt Equation Arithmetic Used on Mixed Filter of Monitored Slope Deformation Data

Abstract:

Assuming the noise from the composition of the white noise and non - white energy limited noise. H filter considers the worst condition of limited energy noise, but the influence of white noise was ignored. At the noise signal and the system norm based on the analysis, using the hybrid filter optimization index J as the optimization goal, and its physical meaning is given. Considering the merit and defect of the H₂and H filter scheme, the filter by Riccati equation solution was established. A simulation example was shown at last. Key words: Mixed filter; Slope deformation monitoring ; Filtering estimation error; Riccati equation
