unknowing

Under the condition that the uncertainties satisfy matching term, and unknowing the bound of uncertainties, the asymptotical tracking control is realized for nonlinear system by means of adaptive robust controller which utilizes variable information of adaptive compensating the uncertainties information of system.

在满足匹配条件下，针对未知不确定界，采用自适应鲁棒控制器，利用自适应变量信息来补偿系统的不确定性信息，实现了非线性系统的渐近跟踪控制。

It expatiated the relevant factors of patients developed depression towards surgery they would be underwent from 4 aspects including unknowing of operation, past operation experience and emotion disturbance, distinctions of personality characteristics, medical and nursing staffs and medical environment.

从对手术的不了解、既往手术体验及情绪障碍、人格特征的差异、医护人员及医疗环境4方面阐述了手术产生抑郁心理的相关因素。

Then, on the premise of unknowing the initial position and orientation, we introduced particle filter into assuming the position and orientation of the robot and successfully realized the global autonomous localization based on the grid map.

然后基于此栅格地图，在初始位姿未知的情况下，引入粒子滤波器对机器人的位姿进行估计，成功实现了机器人的全局定位。
