Weighted Minimum Mean Square Kalman Filter
Miaoliang Zhu · 2009
In order to use Kalman Filter(KF) in nonlinear systems,a new method was proposed.Using the principle that a set of discretely sampled points can be used to form a linear system,the estimator yields performance equivalent to the Extended Kalman Filter(EKF) for nonlinear systems and can be elegantly used to nonlinear systems without the differential steps required by the EKF.We argue that the ease of implementation and more accurate estimation features of the new filter recommend its use in applications.
