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.

该方案在采用 Lagrange 函数建立状态空间方程的基础上，利用能量控制策略实现自动起摆；采用最优控制理论中的极点配置法设计倒立摆系统的控制器；同时利用滑模变结构的等值原理设计观测器，实现对系统未知状态变量的观测。
