外文摘要：This paper brings up an improved high degree cubature H-infinity filter for a class of nonlinear discrete-time systems with non-Gaussian and colored system noises. The proposed H-infinity filter is deduced by introducing the fifth-degree spherical-radial rule into a frame of nonlinear point-based H-infinity filters. Stability analysis demonstrates that the high degree cubature H-infinity filter can effectively improve the stability of standard high degree cubature Kalman filter. Furthermore, the improved filter is contrastively tested in two different classic nonlinear problems with three kinds of uncertain system noises. Simulation results show that the proposed filter achieves better performance in filtering accuracy and robustness than other compared nonlinear filters.
