quadrant error 双语例句

1. In these methods, one is signal recover on some little points of the pulse wave in sampling very narrow signal, It help to acquire the peak value of the pulse; To improve the method of traditional balance adjusting on hardware, design software balance method, spare the four precision amplify circuits, improve the precision and stabilization of the balance adjusting. In traditional detector measure method, it need to adjust the detector to a fiducial position precisely in 3D directions, it waste time and energy of worker, in the thesis, the author use Neural Network calculation method, it can measure the off-focus value in despite of detector fixing error, improve the measurement efficiency four-quadrant photoelectric detector.
   其中，针对瞬态极窄脉冲的采样，提出了信号重构算法，在脉冲采样点较少的情况下完成对脉冲信号的重构，求取脉冲峰值；相比通用的四象限通道硬件电路平衡校正方法，提出了软件平衡校正算法，节省了四路精密放大电路系统，提高了通道平衡校正的精度和稳定性；传统检测技术中需要将四象限探测器在三维方向精细调整到基准状态后才能检测，费时费力，文中提出了采用人工神经网络算法，可以在有安装偏差的情况下直接判读探测器离焦量值，提高了产品的检测效率。
2. Secondly, the performance of the acousto-optic steering system is deteriorated as a result of the coupling because of nonlinear of quadrant detector and the pointing error introduced by satellite platform vibration. For this problem, this paper introduces the model reference adaptive control system, and presents the perfect model. The model reference adaptive controller is designed to force the output of the acousto-optic steering system following the output of the perfect model to improve the system performance. Then the hyperstability theory is used to make sure the adaptive parameters and analyze the stability of the system.
