实现对测量电压信号的卡尔曼滤波功能现代测试系统中，传感器输出的信号以电压信号为主。因此对电压的精确测量是测试系统精确测量系统状态的重要前提。然而由于过程扰动噪声和测量误差使测得的电压值偏离真实的电压值。采用卡尔曼滤波方法可以减小上述误差。-Achieve the Kalman filter functional test system to measure the voltage signal, the sensor output signal to a voltage signal. Therefore, accurate measurement of the voltage test system is an important prerequisite for accurate measurement of the system. However, due to the process of the measured voltage deviation from the real value of the voltage disturbance noise and measurement error. Using the Kalman filtering method can reduce the error.
