Description: The need for accurate monitoring and analysis of sequential data arises in many scientic, industrial
and nancial problems. Although the Kalman lter is effective in the linear-Gaussian
case, new methods of dealing with sequential data are required with non-standard models.
Recently, there has been renewed interest in simulation-based techniques. The basic idea behind
these techniques is that the current state of knowledge is encapsulated in a representative
sample from the appropriate posterior distribution. As time goes on, the sample evolves and
adapts recursively in accordance with newly acquired data. We give a critical review of recent
developments, by reference to oil well monitoring, ion channel monitoring and tracking
problems, and propose some alternative algorithms that avoid the weaknesses of the current
methods. Platform: |

Description: observable distribution grid are investigated. A distribution
grid is observable if the state of the grid can be fully determined.
For the simulations, the modified 34-bus IEEE test feeder is used.
The measurements needed for the state estimation are generated
by the ladder iterative technique. Two methods for the state
estimation are analyzed: Weighted Least Squares and Extended
Kalman Filter. Both estimators try to find the most probable
state based on the available measurements. The result is that
the Kalman filter mostly needs less iterations and calculation
time. The disadvantage of the Kalman filter is that it needs some
foreknowlegde about the state. Platform: |

Description: The Unscented Kalman Filter (UKF) is a novel development in the field. The idea is to produce several sampling points (Sigma points) around the current state estimate based on its covariance. Then, propagating these points through the nonlinear map to get more accurate estimation of the mean and covariance of the mapping results. In this way, it avoids the need to calculate the Jacobian, hence incurs only the similar computation load as the EKF. Platform: |

Description: 一个gps和ins组合导航的matlab程序-kalman-localization
Implementation of localization using sensor fusion of GPS/INS/compass through an error-state Kalman filter.
The MATLAB code borrows heavily Paul D. Groves book, Principles of GNSS, Inertial, and Multisensor Integrated Navigation Systems, his MATLAB code is marked as his, and is held under the BSD license.
This code is very much a work-in-progress as I transition a MATLAB implementation to C++. Until the code is in a stable state, I will make changes based on my own needs, with complete disregard for backwards compatibility. If you liked it, then you shoulda used a fork on github. Following the initial development, I may make it more portable. Platform: |

Description: tIn practice, many estimation problems rely on -line solutions, hence recusive methods are necessary.Tradition estimation approaches for linear systems subject to Gaussian noise are based on the Kalmanfilter and its improving algorithms. Based on the realization construction of state prediction and mea-surement update, Kalman filter can obtain the optimal estimation of state under the linear minimumvariance criterion. However, it is known that the optimal filtering result is achieved in statistical sense,which can not meet a superior result for single filtering process because of the random characteristicseffect of measurement noise. Aiming at this problem, the authors propose a novel Kalman filtering algo-rithm based on measurement bootstrapping strategy-tIn practice, many estimation problems rely on on-line solutions, hence recusive methods are necessary.Tradition estimation approaches for linear systems subject to Gaussian noise are based on the Kalmanfilter and its improving algorithms.

Description: A novel method based on a combination of the Extended Kalman Filter (EKF) with Particle Swarm Optimization (PSO) to estimate the speed and rotor flux of an induction motor driveis presented. The proposed method will be performed in two steps. As a first step, the covariance matrices of state noise and measurement noise will be optimized in an off-line manner by the PSO algorithm. As a second step, the optimal values of the above covariance matrices are injected in our speed-rotor flux estimation loop (on-line).Computer simulations of the speed and rotor-flux estimation have been performed in order to investigate the effectiveness of the proposed method. Simulations and comparison with genetic algorithms (GAs) show that the results are very encouraging and achieve good performances. Platform: |
