For multi-model multisensor systems with uncertain-covariance multiplicative and additive white noises, a universal fictitious noise-based Lyapunov equation approach is presented, by which the original system can be converted into one with only uncertain additive noise variances. According to the minimax robust estimation principle, based on the worst-case system with conservative upper bounds of...
For multi-model multisensor systems with uncertain covariance linearly correlated white noises, the design problems of the robust weighted fusion steady-state Kalman estimators (predictor, filter, smoother) are addressed. According to the minimax robust estimation principle, applying Lyapunov equation approach, a unified direct design approach to obtain the local and three weighted fusion robust steady-state...
H-bridge converter, an important topology which is widely used in power electronics, has complex nonlinear phenomena. It has important theoretical and practical significance to explore the mechanism of nonlinear behaviors in H-bridge converter. Bifurcation and chaos phenomena in H-bridge DC chopper under peak-current programmed are studied in this paper. First, iterative map of H-bridge DC chopper...
