In the following , four parts of the system are introduced , including implement machine , positioning control , measurement system with ccd and operation software 从执行机构、定位控制、 ccd测量系统和软件实现4个部分，实现了系统的构建。
Based on the untethered auv developed by our institute , this paper analyzes the navigation control and the position control methods of auv 摘要以成功研制的无缆自治水下机器人( auv )为基础，对其航行控制和定位控制方法进行了较详细的分析。
The common point of motion control system lies in its position control to working axes . the axes could be positioned according to another axes or coordinate system 此轴可以相对于某一主轴（主轴定位）或相对于某个坐标系统（坐标系统定位）进行定位控制。
6 . the simulation test and practical test on the lake has been finished about the dynamic positioning control system concerned in this paper , which has been delivered to the consumer 6 )完成了本文研究的动力定位控制系统的仿真试验及湖上试验，并已交付用户使用。
Simulation results of the fuzzy adaptive control method in the location control and the trajectory tracking with different tip disturbances are presented and compared with the results of the classic pd control 在柔性操作臂末端带有不同载荷的情况下，分两种类型进行了控制仿真实验：定位控制和轨迹跟踪控制。
When there is random error in input data , if position - keeping plan is applied , thrusters will change working status in high frequency that will lead to sever thrust wear and energy waste 当输入存在随机误差的情况下，采用常规的定点定位控制方法会导致推进器频繁改变状态，造成不必要的机械磨损，浪费很大的能量。
With the embedded pc controlling , the control level of the automatic cutter is developed highly . with the digital servo - system , the exact control is developed in the exact length and connect of the automatic cutter 采用嵌入式pc作为控制式计算机来提高自动裁断机的控制水平，用位置伺服系统来改进自动裁断机的定长和对接的精确定位控制。
