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...

Time-Invariant State Feedback Control Laws for a Special Form of Underactuated Nonlinear Systems Using Linear State Bisection

Linear state bisection is introduced as a new method to find time-invariant state feedback control laws for a special form of underactuated nonlinear systems. The specialty of the systems considered is that every unactuated state should be coupled with at least two directly actuated states. The basic idea is based on bisecting actuated states and using linear combinations with adjustable parame...

A Markov Game Controller for Finite State Space Nonlinear Systems

The optimal control problem for nonlinear systems, in presence of external disturbances, has been formulated as a two-player zero-sum Markov game between the disturbance and the control. In Reinforcement Learning (RL) paradigm, controller design for nonlinear systems has been framed either using the Markov Decision Process (MDP) setting or the H∞ theory. While MDP framework assumes a stationary...
