查询词典 control space

Urban forest is the lively infrastructure of a city. As citifying process develops, it is impossible to develop large-scale green land in the downtown of a city. What s more, the efficient city ecological green-land system, which doesnt equal to the simple that expansion, requires considerable proportion of suburb green space and city forest resources, in order to deeply control the space-time development of those resources and accurately understand the various influence that natural and unnatural factors bring to those resources.

城市森林是有生命的城市基础设施，随着城市化进程的推进，城市中心区不可能大规模地发展绿地，而且，高效的城市生态绿地系统不是简单的成片扩展，要求含有相当比例的近郊绿色空间和市域林带，因此，为了更好地掌握城市森林资源的时空动态，准确了解自然因素和非自然因素对城市森林资源产生的各种影响，就必须对城市森林资源实施动态监测。

Reaction wheel or reaction thruster is employed to maintain the attitude of the base of space robot fixed in attitude control of free-flying space robot.

自由飞行空间机器人的姿态控制可考虑利用反作用轮或反作用喷气装置以维持机器人本体姿态不变，但这种方法存在的最大问题是消耗燃料，直接影响机器人的轨道寿命，同时对系统产生振动而导致系统不稳定。

与传统的基于机器人末端力／力矩信息的笛卡尔阻抗控制方案不同，考虑了5种基于关节力矩的笛卡尔阻抗控制方案，包括笛卡尔空间／关节空间基于力的、笛卡尔空间／关节空间基于位置的方案和刚度控制。

First, the state～space equation of the circular inverted pend ulum system was established based on the Lagrange Equation. On the base of that, the circular inverted pendulum was swung up by the energy control strategy, and the controller of the system was designed by the pole placement of the optimal control theory. Second, in order to realize the observation for the unknown vari ables, stable state observers were designed based on the equivalent principle of sliding mode variable structure.
