卡尔曼静态滤波在GPS量测数据中的应用。静态模型以待测点的位置和速度作为状态变量，假定系统噪声和量测噪声为高斯白噪声。多数情况下将其看成是一个线性系统。( Application of Calman static filtering in GPS measurement data. The static model is used as the state variable, and the system noise and measurement noise are Gauss white noise. In most cases, it is considered as a linear system. )

说明：  MATLAB仿真永磁同步电机直接转矩控制，传统滞环+开关表控制，仿真效果很好(The direct torque control of permanent magnet synchronous motor is simulated by MATLAB, and the traditional hysteresis plus switching table control has a good simulation effect.)
