The second, most of the previous works cannot satisfy the interactive, realizing and real-time request at the same time even though in the single pendulum assumption.

第二，即使在基于单摆模型的情况下，可交互性，实时性和真实感三者在树的动画生成系统很难被同时满足。

The simulation experiments on the second subsystem of the inverted pendulum show that the effect on improving tracking performance is prominent and the controller's design is reasonable and available.

对倒立摆二阶子系统的仿真，实验表明跟踪性能改善的效果是明显的，证明控制器的设计是合理和有效的。

The second strategy don't use mathematics model of inverted pendulum, make use of fuzzy theories to control swinging up automatically and the balance controlling directly.

第二种策略不利用倒立摆的数学模型，直接利用模糊控制对其进行自动起摆和平衡控制。

"The atomic clock is actually putting out an electronic signal which is essentially analogous to the ticking of a pendulum clock... which might tick once every second or once every couple of seconds, " says Dr McCarthy.
