Iterated Invariant EKF for Quadruped Robot Odometry
CoRRKalman filter-based algorithms are fundamental for mobile robots, as they provide a computationally efficient solution to the challenging problem of state estimation. However, they rely on two main assumptions that are difficult to satisfy in practice: (a) the system dynamics must be linear with Gaussian process noise, and (b) the measurement model ...

Li-ion battery SOC estimation and test research based on EKF
, 2015 锂离子电池以其无泄漏、无污染、无噪声等优点,近年来广泛应用于工业及生活领域。目前常用的基于扩展卡尔曼滤波(EKF)的锂电池SOC(荷电状态)估计方法由于建模不准确而导致估计结果误差较大,严重影响到电池管理系统的性能及整机系统的控制。针对该问题,采用精度较高的Randles模型,并在拟合电池的OCV(开路电压)-SOC曲线时通过引入自然指数函数并增加多项式阶数等方法提高拟合精度。使用EKF对锂电池SOC进行估计,与理论结果相比模型改进后估计误差的标准差比改进前下降了64.43 ...

Sammenligning av EKF- og UKF- kalmanfilter anvendt på totankprosess [PDF]
, 2009 Denne masteroppgaven er todelt. Del I går ut på å sammenligne ytelsen til et utvidet Kalmanfilter (EKF) og et "unscented" Kalmanfilter (UKF) på et prosessanlegg bestående av to tanker, ved Universitetet i Stavanger (UIS).

Application of EKF for an electro-hydraulic servo system using model-based approach
, 2013 This paper works on extended Kalman filter (EKF) for model-based fault detection of an electro-hydraulic system to deal with stochastic behaviour during control. A mathematical model of an electro-hydraulic system is developed. Some faults are introduced
