Specifically, the main contributions of this work are as fol- lows: (1) in linear-nonlinear measurement system, H ∞ filter is integrated into SR-CKF, and square-root cubature H∞ Kalman filter (SR-CH∞KF) is established; (2) Euler angle measurement model is used in SR-CH∞KF, and ...
“writing and drawing bear the same root”) is less of a commentary on style, but rather a reflection of semiotics. The way in which the Chinese character “shan” (“mountain”) is written is comparable to the way in which one would draw a mountain. Despite the evolution of ...

Improved square-root cubature Kalman filtering 1 (ISRCKF1) introduces an innovation that first obtains the unknown input estimates from the measurement equation, then updates the innovation to derive the unknown input estimates from the state equation, then uses the already obtained estimates of the ...
At the same time, in the filtering process, the recursive update is directly performed in the form of the square root of the covariance matrix to reduce the computational complexity and to ensure the nonnegative definiteness of the covariance matrix, which effectively avoids the divergence of the...
Answer to: Use an integral to estimate the sum sum_i = 1^10000 square root i. By signing up, you'll get thousands of step-by-step solutions to your...
In the unknown time-varying noise, non-linear target-vehicle tracking faces the problem of low precision. Based on the square-root cubature Kalman filter (SRCKF), the Sage–Husa noise statistic estimator and the fading memory exponential weighting method are combined to derive a time-varying ...
. . , n. (24) √ Here Pk s is the sth column of the matrix square root of Pk, and is the scaling parameter [34]. Thus, the UT estimate zˆUk T is represented by known functional of the Kalman estimate xˆk and error covariance Pk. 4. Numerical Verification In this section,...
