上研究生时写的扩展卡尔曼滤波程序（EKF），带测试例子，可编译执行-When the graduate writing program of the extended Kalman filter (EKF), with the test example, the implementation can be compiled

edk 使用了matlab中s函数编写，比较好简洁-edk used in the preparation of matlab s function, simple is better

使用S-function搭建的车辆状态估计simulink模型，包含EKF和CKF(Simulink model of vehicle state estimation using S-Function, including EKF and CKF)

基于EKF的三相PMSM无传感器矢量控制框图，EKF算法采用s函数进行编写，函数命名为EKF。其中，输入为电机在静止坐标系下的钉子电压和定子电流，输出为定子电流估计值，转速和转子位置(Based on EKF's three-phase PMSM sensorless vector control block diagram, EKF algorithm uses s function to write, and the function is named EKF. Among them, th
