测量噪音 meaning in Chinese

measurement noise

The precision and convergence of both rotor speed and flux estimation with ekf largely depend on the accuracy of the models of system noise and measurement noise . a global optimized noise covariance estimation method based on genetic algorithms ( ga ) is applied to ekf in foc system , a ga training simulation system of optimal parameters of ekf is given and the simulation results proves the effectiveness and robust of this algorithms
本文用遗传算法( ga )对全闭环矢量控制系统中的ekf噪音模型进行离线优化辩识，仿真结果表明， ga寻优到的噪音模型使采用卡尔曼滤波器的无速度传感器矢量控制系统获得了与带速度传感器矢量控制系统相类似的动态性能，全系统对消息噪音和测量噪音有好的鲁棒性。
