After full investigation on development status of modern distance education in our country , combining with advanced quality management theory and control concept , we put forward the basic notion of practicing modern distance education quality control 在全面考察我国现代远程教育发展状况的基础上,结合先进的质量管理理论和控制思想,提出现代远程教育实施质量控制的基本思路。
4 . a new control concept and strategy for poly - pump system and its corresponding topological configuration are suggested . using on - the spot bus communication technology to improve flexibility and efficiency of group control for pv water pumping 提出了光伏水泵系统的群控概念及其相应的拓朴结构,研究了相应的优化控制策略,设计并实现了现场总线通讯技术,进一步提高了群控系统的灵活性及提水效率。
The iterative learning control has been raised as a new control concept . by correcting the current control command using the previous system error data instead of the exact system parameters , iterative learning control can effectively suppress the vibration of the highly periodic system 迭代学习控制不需知道系统的具体动力学参数,只要系统运动具有一定周期性,它便能利用系统先前的控制经验和输出误差来修正当前的控制信息,从而达到良好的控制效果。
The inverse kinematics of a space - based manipulator composed of three rigid bodies with prismatic joint are studied in the second chapter , and the jacobean matrix for space manipulator is derived by fully cartesian coordinates . a control method for space manipulator based on the resolved motion rate control concept is proposed 为此结合系统动量及动量矩守恒关系导出了以完全笛卡尔坐标表示的系统运动jacobi矩阵,并在此基础上研究了带滑移铰空间机械臂的分解运动速度控制方法,给出了计算机数值仿真算例,以此证明了该方法的有效性。
It is demonstrated by simulations that the control method is efficient and the fully cartesian coordinates is practically efficient . then the inverse kinematics of dual free flying space manipulator are mainly discussed in the third chapter , and the jacobean matrix for dual manipulator space robot is derived by fully cartesian coordinates , a control method for space manipulator based on the resolved motion rate control concept is proposed . then , the computer simulation verifies the effectiveness of the algorithm 首先,分析了闭环双臂空间机器人捕捉目标物体时的运动学关系,给出了以完全笛卡尔坐标表示的系统运动jacobi关系;然后,以此为基础研究了空间机器人双臂协调操作的分解运动速度控制方法和协调操作问题;最后应用matlab语言对平面双臂空间机器人系统进行了计算机模拟、仿真,仿真运算证实了上述方法的有效性。
It is demonstrated that the problems , such as incompletion of the auxiliary facilities concerned , difficult to control both the safety and the risk and imperfection of the non - engineering measures etc . , are to be solved through the changeover of the water control concept and strengthening the related risk management during the practice of the flood resourcification 在开展洪水资源化的实践中,应通过转变治水思路、加强风险管理,去解决工程设施不配套、安全与风险难以控制、非工程措施不完善等问题。
