卡尔曼滤波（Kalman filtering）一种利用线性系统状态方程，通过系统输入输出观测数据，对系统状态进行最优估计的算法。由于观测数据中包括系统中的噪声和干扰的影响(Calman filter (Kalman filtering), an algorithm for optimal estimation of system states using linear system state equations and input and output data of the system. The observation data include the influence of noise and interference in the system)
