kalman filter design


A Kalman filter is an optimal estimator – ie infers parameters of interest from indirect, inaccurate and uncertain observations. It is recursive so that new measurements can be processed as they arrive. (cf batch processing where all data must be present).

In putting together this course pack we decided not to simply include copies of the slides for the course presentation, but to attempt to put together a small booklet of information that could stand by itself. The course slides and other useful information, including a new Java

Stochastic stability of the discrete-time extended Kalman filter
free download

In this paper, the authors analyze the error behavior for the discrete-time extended Kalman filter for general nonlinear systems in a stochastic framework. In particular, it is shown that the estimation error remains bounded if the system satisfies the nonlinear observability rank

Indirect Kalman filter for 3D attitude estimation

The subject of this thesis is the development of the design for a specially-organized, general- purpose computer which performs matrix operations efficiently. The content of the thesis is summarized as follows: First, a review of the relevant work which has been done with

Assimilation of simulated Doppler radar observations with an ensemble Kalman filter .
free download

Assimilation of Doppler radar data into cloud models is an important obstacle to routine numerical weather prediction for convective-scale motions; the difficulty lies in initializing fields of wind, temperature, moisture, and condensate given only observations of radial

Gaussian distribution is the most popular distribution in modeling the uncertainty in the system. By the central limit theorem, any sum or average of samples from ANY distribution (with finite mean and standard deviation) will be approximately Gaussian with the

A quaternion-based unscented Kalman filter for orientation tracking
free download

E Kraft- Proceedings of the Sixth International Conference of natanaso.github.io This paper describes a Kalman filter for the real-time estimation of a rigid body orientation from measurements of acceleration, angular velocity and magnetic field strength. A quaternion representation of the orientation is computationally effective and avoids

Beyond the kalman filter : Particle filters for tracking applications

Target tracking is an important element of surveillance, guidance or obstacle avoidance, whose role is to determine the number, position and movement of targets. The fundamental building block of a tracking system is a filter for recursive state estimation. The Kalman filter

Fractional Kalman filter algorithm for the states, parameters and order of fractional system estimation

This paper presents a novel method for hand tracking. It uses a 3D model built from quadrics which approximates the anatomy of a human hand. This approach allows for the use of results from projective geometry that yield an elegant technique to generate the projection of

Neural decoding of cursor motion using a Kalman filter
free download

The direct neural control of external devices such as computer displays or prosthetic limbs requires the accurate decoding of neural activity representing continuous movement. We develop a real-time control system using the spiking activity of approximately 40 neurons Background In 1960, Rudolf E. Kalman published his famous paper describing a recursive solution to the discrete-data linear filtering problem . Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research

Evaluating the performances of adaptive Kalman filter methods in GPS/INS integration
