| 14155 | 采用特征投影的方法可以实现方向图在主瓣上保形同时抑制旁瓣干扰,但当主瓣干扰强度与旁瓣干扰信号强度相当时,该算法的性能显著降低。 | The eigen-projection matrix processing algorithm can be used to maintain the mainlobe pattern while suppressing sidelobe interference.However,the performance is significantly reduced in the situation that the power of the mainlobe interference is on the same level as the sidelobe jamming. |
| 14156 | 针对这一问题,提出了一种主瓣干扰特征向量空间重构的方法,来实现主瓣保形并且抑制旁瓣干扰,对强主瓣干扰与弱主瓣干扰采用不同的方式计算其特征向量并共同构建主瓣干扰特征向量空间,再采用特征投影的方式对协方差矩阵预处理,并根据MVDR准则计算自适应权值。 | In order to solve this problem,a new method is proposed by reconstructing the mainlobe interference eigenvector space. Different methods are used for calculating the eigenvectors corresponding to the strong and weak mainlobe interferences, which jointly construct the mainlobe interference eigenvector space. Then, the covariance matrix is pre-processed by the eigen-projection matrix,and the adaptive weight vector is calculated according to the MVDR criterion. |
| 14157 | 仿真验证了在同时存在强主瓣干扰与弱主瓣干扰时,该方式能有效地在旁瓣干扰处产生零深且主瓣方向保形。 | Simulation result shows that: the algorithm effectively maintain the mainlobe pattern while suppressing sidelobe interference when there are both strong and weak mainlobe interferences. |

| 14159 | 首先建立了包含执行器故障、输入受限以及外界干扰的四旋翼UAV位置模型和姿态模型。 | Firstly, the position model and attitude model of quad-rotor UAV including actuator fault, input constraints and external interference are established. |
| 14160 | 然后分别对位置环和姿态环进行了分析,采用滑模滤波器对虚拟控制指令滤波,并利用模糊系统逼近法估计出不确定项,设计了鲁棒容错控制律。 | Then, the position loop and attitude loop are analyzed respectively, and the virtual control command is filtered by sliding mode filter. The uncertainty is estimated by fuzzy system approximation method,and the robust fault-tolerant control law is designed. |
| 14161 | 最后证明了位置环和姿态环的稳定性。 | Finally, the stability of the position loop and the attitude loop is proved. |
| 14162 | 仿真实验结果表明：提出的鲁棒容错控制方法能够在输入受限下快速准确跟踪指令信号,与积分滑模容错控制律相比具有更好的控制效果,实现了包容执行器故障和外界干扰的全状态鲁棒容错控制。 | The simulation results show that the proposed robust fault-tolerant control method can quickly and accurately track the command signal under input constraints,and has better control effects than integral sliding mode fault-tolerant control law,which realizes the full-state robust fault-tolerant control including actuator fault and external interference. |
| 14163 | 在移动空间光通信中,激光光斑中心的快速捕获至关重要,传统灰度重心算法很难满足高速移动空间光通信的捕获要求。 | In the mobile space optical communication,the fast capture of laser spot center is very important,but it is difficult to satisfy the requirement by using the traditional grayscale gravity center algorithm. |
| 14164 | 针对传统灰度重心算法提出了一种优化方案,在计算光斑中心前加入了滤波去噪、自适应二值化阈值处理,可有效提高系统抗干扰特性；经过粗识别光斑中心位置,选框重心计算,提高了检测光斑中心的速度和精确度。 | In this paper,an optimization scheme is proposed. Filtering de-noising and adaptive binaryzation threshold processing are added before calculating the spot center,which can effectively improve the anti-interference performance of the system. The speed and accuracy of spot center detection are improved by coarse identification of spot center and gravity center calculation. |
