查询词典 filter flask

For the problem that the extended Kalman filter is difficult to design and prone to diverge, the unscented Kalman filter algorithm based method is presented to solve the problems of the filter design and convergence. The error from the low-cost inertial gyro and accelerometer is compensated to achieve optimal attitude estimation. The filtered model is applied to the two-wheeled self-balanced robot system.

对这两个部件采取的相应措施是：①在针阀前设置多级过滤器，过滤器滤网孔目逐级缩小，以截留固体颗粒杂质；②橡胶隔膜采用优质产品，并定期检查隔膜和水力控制阀内弹簧的情况。

This paper introduces a novel technique for estimating the signal power spectral density to be used in the transfer function of a microphone array post-filter.The technique is a modification of overestimation of noise power spectral density of the existing Zelinski post-filter and McCowan post-filter,which utilize the auto- and cross- spectral densities of the signals.Near-field compensation is taken into account.

介绍了一种用于近场麦克风阵列后滤波语音增强的方法，避免了现有的利用自功率谱密度和互功率谱密度的Zelinski和McCowan后滤波器中噪声功率谱过估计的问题，并加入了近场传播的幅度衰减补偿和相位延迟补偿。
