姿态信息是飞行控制中最关键的参数之一,因此姿态测量成为飞行控制系统首要解决的问题。利用多M EM S传感器研制了一种微型姿态测量系统。利用三轴M EM S加速度计和三轴M EM S陀螺数据,由方向余弦矩阵的姿态表示形式推导了扩展K a lm an滤波方程,解算出飞行器的俯仰角和横滚角;设计专家系统判断飞行器的运动状态,并根据该状态调整滤波算法中的测量噪声矩阵,使系统可同时满足静态情况和动态情况的使
The current network-on-chip (NoC) topology cannot predict subsequent switch node status promptly. Switch nodes have to perform various functions such as routing
Variations of gene expression and DNA sequence are genetically associated.The goal of this study was to build genetic networks to map from SNPs to gene expressi
