Through the theoretical derivation and linear matrix inequality ( lmi ) , we obtain sufficient conditions for the robust stability of the closed - loop system 通过理论分析与求解线性矩阵不等式,文章得出使闭环控制系统鲁棒稳定的充分条件。
In chapter four , the casimir energy for various string loop systems , such as closed bosonic strings , multiloop strings and connected string loops was calculated 计算了它们的c社s加,计能量,并将所得到的不同体系的cas1mir能量进行对比。
According to the high or low of the energy , we can decide what system is more stable . furthermore we can also know the direction in string loop system evolution 由能量的高低来判别哪些闭弦体系更稳定,从而推知闭弦体系演化时将遵循的方向。
An undersea fibre optic cable stretching from china to the united states in a loop system more then 25 , 000 kilometres underwater will soon expand china ' s links with the world 超过2万5千公里在水面下的中美海底光纤循环系统将把中国和世界连接起来。
The global asymptotical tracking of given trajectories is achieved and the boundedness of all signals of the resulted closed - loop system is also guaranteed 两种设计方案都实现了对给定目标轨线的全局渐近跟踪,保证了闭环系统所有信号全局一致有界。
3 ) implement cascade control system to regulate wheel speed by dsp and motor driver instead of ordinarily single closed loop system 3 )改进了机器人轮速控制的单闭环控制系统,通过dsp和电机驱动芯片,实现机器人轮速的串级控制结构,改善了控制效果。
When ( c , a , b ) is a minimum phase system with relative degree r > 1 , we present a new method of constructing a dynamic compensator such that the closed loop system is asymptotically stable 当系统的确定性部分为最小相位系统时,提出了一种构造动态补偿器的新方法。
Discussing the influence of the electrostatic force upon the system function making good use of this electrostatic force , we can design to open - loop system and closed - loop servo system 讨论了静电力对系统性能的影响,合理利用静电力可以设计出开环和闭环控制系统。
The frizzy logic control is used to estimate the unknown uncertainties , and guarantees the robustness of the closed - loop system in the reaching phase synchronously 模糊逻辑控制用来估计系统未知的不确定性因素,并同时保证了闭环系统在变结构控制到达阶段的鲁棒性。
Data acquisition system is a closed loop system which converts analog signals into digital signals to analyze , deal with , memory , display and treat with alarms 数据采集系统是把模拟信号转换成数字信号,并通过计算机进行分析、处理、存储、显示和报警处理的闭环系统。
