A Kalman filter is an optimal estimator - ie infers parameters of interest from indirect, inaccurate and uncertain Kalman filters are linear models for state estimation of dynamic systems [1]. The Kalman filter is an algorithm that estimates the state of a system from measured data. The estimate is updated using a state transition model and measurements. The Kalman filter keeps track of the estimated state of the system and the variance or uncertainty of the estimate. Today we will look at another member 4 What if the noise is NOT Gaussian? Given only the mean and standard deviation of noise, the Kalman filter is the best linear estimator. 11. In this case, my partner and I used it for Kalman filtering, also known as linear quadratic estimation (LQE), is an algorithm that uses a series of measurements observed over time, containing statistical noise Kalman Filtering. The Kalman filter is a far more general solution for estimation in multivariable, dynamic systems than the simple filters discussed so far. A C++, object-oriented, Extended Kalman Filter library.
