Wikipedia writes: In the extended Kalman filter, the state transition and observation models need not be linear functions of the state but may instead be differentiable functions. WebApplying the extended Kalman filter (EKF) to estimate the motion of vehicle systems is well desirable due to the system nonlinearity [13,14,15,16].The EKF linearizes the nonlinear model by approximating it with a first−order Taylor series around the state estimate and then estimates the state using the Kalman filter.
