| 摘 要： | 传统的GPS接收机设计较为固定,用户不能改变接收机各类参数以适应不同导航信号处理的需要.而软件接收机只需做较小改动就可以适应不同信号,能够迅速分析、仿真、实现各类算法.在GPS软件接收机的基础上,利用鉴频器辅助鉴相器的输出,引入一个模糊逻辑控制器,使得环路能够智能跟踪GPS信号的动态变化.实验结果证明所提出的设计方法与传统环路相比可大幅度缩短跟踪时间,减小环路滤波器带宽,并能消除周跳. |

| Abstract: | Minimal invasive surgery assisted robot was developed in Robotics Institute in Beijing University of Aeronautics and Astronautics.Based on the requirement of neurological stereotactic surgery,dexterity of the robot was analyzed.Using concept of service sphere and service section,definition of dexterity was proposed at any point inside the workspace of the five degree-of-freedom robot,then,analysis method of workspace dexterity was proposed.Dexterity distribution within the workspace was given using numerical analysis and graphical display,and the result was verified through experiment on the robot physical prototype.With the help of dexterity distribution in workspace,reliable reference can be supplied for surgery operation planning. |
| Keywords: | software global position system receivers fuzzy logic controller carrier tracking loop |
