This paper describes a new approach for generalizing the Kalman filter to nonlinear systems. A set of samples are used to parametrize the mean and covariance of a (not necessarily Gaussian) probability distribution. The method yields a filter that is more accurate than an extended Kalman filter (EKF) and easier to implement than an EKF or a Gauss second-order filter. Its effectiveness is demonstrated using an example.

Kalman Filtering for a Generalized Class of Nonlinear Systems and a New Gaussian Quadrature Technique
The class of nonlinear systems treated in this technical note consists of the discrete time non linear systems that are formed by the interconnection of linear systems through static nonlinearities with few inputs, and a new quadrature scheme suitable for nonlinear Kalman filtering is introduced.
