一、扩展卡尔曼滤波(EKF)简介 扩展卡尔曼滤波(Extended Kalman Filter)是建立在经典卡尔曼滤波算法的基础上。核心思想是,对一般非线性系统,首先围绕滤波值Xk~将非线性函数f(∗)和h(∗)展开成Taylor级数但只保存一阶及以下部分(舍去二阶及以上项),得到近似的线性化模型。然后就是利用kalman滤波算法完成对目标的...
所以可以完全套用前面的框架,就可以得到我们在加性条件下的EKF:预测步:mk−=f(mk−1),Pk−=Fx(mk−1)Pk−1Fx⊤(mk−1)+Qk−1.更新步:vk=yk−h(mk−
“Engineers can solve exact problems using numerical approximations, or they can solve approximate problems exactly" - Fred Daum. 对出现在实际问题中的非线性的运动学(dynamic)模型以及/或 非线性的观测方程进行线性化的操作,然后基于这个线性化的方程计算卡尔曼增益,是EKF的精髓(philosophy)所在。相反,ESKF通过...

Extended Kalman filterFor a lithium battery, a second-order equivalent circuit model is adopted by studying the battery characteristic, and a state space equation with state of charge (SOC) being one state is constructed. To promote the SOC estimation precision of the extended Kalman filter (EKF...
Both UWBbaseddistance estimates and RSS measurements based onZigBee are simultaneously processed by an Extended KalmanFilter (EKF). Moreover, a low cost inertial device is also usedto acquire acceleration measurements which proved to beuseful in order to detect the motion of the mobile node. This...
