agitation error
Examples
- As the perturbation analysis , we make some results on the singular linear equations " condition number concerned with the generalized inverse at , s , ( 2 ) which extend the results on the nonsingular linear equations " condition number , then we give the perturbation bound for the solutions of ep linear equations
在奇异线性方程组解的扰动分析方面，我们首先从最具有代表性的广义逆a _ ( ts ) ~ ( 2 )着手，建立了有关求解奇异线性方程组的条件数的表达式，从而推广了非奇异线性方程组的条件数的一些结果，然后我们对ep线性方程组的广义逆解的相对扰动误差界给出一个估计式。 - The feedbacks of position , velocity , acceleration and dynamic pressure were applied to adjust the model , so the control system of single jar electrodraulic servo mechanism was built . to reduce the system error and interference error , the compound control was designed . the results of simulations showed that the magnitude attenuation and phase lag of the system come to the project demand
引入包括位置反馈、速度反馈、加速度反馈和动压反馈在内的反馈控制技术对电液伺服驱动机构模型进行综合校正,从而建立单缸电液伺服控制系统,并在分析系统误差和扰动误差后,加入复合控制减小系统误差和抑制干扰,仿真结果表明复合控制系统的控制品质有了明显改善,能够满足工程需求。 - We highlight the key points of this dissertation at the end of this charter . in chapter 2 , a modified projection transformation method is presented , which utilizes preliminary estimation of interference doa . it is demonstrated that the side lobe performance of adapted antenna patterns can be significantly improved with this method and increased convergence rate of adaptive algorithm when the array manifold is not known exactly
针对投影预变换在大信噪比时性能下降的缺点，提出了一种改进的基于投影预变换自适应波束形成算法，通过对阵列协方差矩阵进行降维处理，既可抑制扰动误差又可降低运算量，增强阵列的sinr输出，具有良好的波束合成性能和较快收敛速度。
