Rotated Unscented Kalman Filter for Two State Nonlinear Systems
In the several past years, Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) havebecame basic algorithm for state-variables and parameters estimation of discrete nonlinear systems.The UKF has consistently outperformed for estimation. Sometimes least estimation error doesn't yieldwith UKF for the most nonlinear systems. In this paper, we use a new approach for a two variablestate no...
متن کاملRobust $mathcal{H}_infty$ Observer-Based Controller for Lipschitz Nonlinear Discrete-Time Systems with Parameter Uncertainties
This note focuses on the design of an observerbased controller for a class of Lipschitz nonlinear discretetime systems with parameter uncertainties. Thanks to the reformulated Lipschitz property [1] that take into account all the properties of the nonlinearities of the system combined with some mathematical tools, it is shown that the solution of the discrete-time output feedback problem, expre...
متن کاملKalman Filters for Nonlinear Systems and Heavy-Tailed Noise
This thesis is on filtering in state space models. First, we examine approximate Kalman filters for nonlinear systems, where the optimal Bayesian filtering recursions cannot be solved exactly. These algorithms rely on the computation of certain expected values. Second, the problem of filtering in linear systems that are subject to heavy-tailed process and measurement noise is addressed. Expecte...
متن کاملNonlinear state observers and extended Kalman filters for battery systems
The focus of this paper is to develop reliable observer and filtering techniques for finite-dimensional battery models that adequately describe the charging and discharging behaviors. For this purpose, an experimentally validated battery model taken from the literature is extended by a mathematical description that represents parameter variations caused by aging. The corresponding disturbance m...
متن کاملAdaptive robust control of nonlinear systems with dynamic uncertainties
In this paper, the discontinuous projection-based adaptive robust control (ARC) approach is extended to a class of nonlinear systems subjected to parametric uncertainties as well as all three types of nonlinear uncertainties—uncertainties could be state-dependent, time-dependent, and/or dynamic. Departing from the existing robust adaptive control approach, the proposed approach differentiates b...
