Synthetic velocity measurement algorithm of monocular vision based on square-root cubature Kalman filter

Review of Scientific Instruments, 2022
The velocity measurement algorithm based on vision is widely used in unmanned aerial vehicle navigation. Under uneven illumination intensity distribution, the traditional Lucas–Kanade (LK) optical flow (OF) algorithm has problems arising from low computational accuracy and poor adaptability.

A Non-singleton Type-3 Fuzzy Modeling: Optimized by Square-Root Cubature Kalman Filter

Intelligent Automation & Soft Computing, 2023
In many problems, to analyze the process/metabolism behavior, a model of the system is identified. The main gap is the weakness of current methods vs. noisy environments. The primary objective of this study is to present a more robust method against uncertainties.

Square root cubature Kalman filter for stocchastic metabolic/ hemodynamic model identification

2017 5th International Conference on Electrical Engineering - Boumerdes (ICEE-B), 2017
Based on clinical data collected using different brain imaging and recording techniques, brain researchers built mathematical models of the activity in the human brain. To test these models they simulate them by performing on those models a virtual brain experiment and compare the outputs from those with the real brain activity recordings.

Passive Location of Angle Sensors Using Extend Square-Root Cubature Kalman Filter

Applied Mechanics and Materials, 2011
A new nonlinear filter method Cubature Kalman Filter (CKF) is improved for passive location with moving angle-measured sensors’ measurements.Firstly,it used Empirical Mode Decomposition (EMD) algorithm to estimate measurement noise covariance; And then the covariance of the procession noise and measurement noise is brought into the circle; Meanwhile ...

Induction Motors Fault Detection Using Square-Root Transformed Cubature Quadrature Kalman Filter

IEEE Transactions on Energy Conversion, 2019
This paper proposes a novel approach for simultaneous state estimation and broken rotor bars (BRBs) detection in induction motors. The proposed method is named square-root transformed cubature quadrature Kalman filter (SR-TCQKF). The accuracy of the filter has been improved by a transformation on the filter's sigma points, whereas the filter becomes ...

Order Tracking by Square-Root Cubature Kalman Filter with Constraints

2016
Condition monitoring of mechanical systems is an important topic for the industry because it helps to improve the machine maintenance and reduce the total operational cost associated. In that sense, the vibration analysis is an useful tool for failure prevention in rotating machines, and its main challenge is estimating on-line the dynamic behavior due

INS/GPS tightly integrated algorithm with Reduced Square-Root Cubature Kalman Filter

2016 35th Chinese Control Conference (CCC), 2016
Focusing on the problem about the real time of nonlinear model's calculation, we propose to use the Reduced Square Root Cubature Kalman Filter (RSCKF) to improve the operating rate of INS/GPS tightly integrated navigation system. This reduced arithmetic simplify the Square Root Cubature Kalman Filter (SCKF) in Time Update step, it directly use the ...

Adaptive points range Square-root Cubature Kalman filter for mars approach navigation

Proceedings of the 33rd Chinese Control Conference, 2014
The navigation accuracy in approach phase has a significant effect on the successful capture and injection of the Mars spacecraft. On one hand, the perturbation of Mars gravity field on spacecraft's orbit increases when spacecraft gradually approaches the Mars, which results in slow change of the orbit dynamic model.

Robust square-root cubature Kalman filter based on Huber’s M-estimation methodology

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2014
In practical engineering applications, the performance of the standard cubature Kalman filter (CKF) and its square-root version can be severely degraded due to outliers in measurement or contaminated distribution. In order to address the problem, a robust version of CKF is presented using Huber’s M-estimation methodology and square-root filtering ...
