In order to provide theoretical basis for the parameter of design on a new type of vibration generator, this parameter of design is seen as a double-body pendulum and mathematical model.
为了给一种新型振动机的参数设计提供理论依据，将其抽象为双物理摆的力学、数学模型。

The value of trainingvs. the value of practicality of mathematical education and the value of know- ledge vs. the value of ability of mathematical education have always been in pendulum.
数学教育的“训练价值”与“实用价值”、“知识价值”与“能力价值”一直处在“钟摆”与“嬗变”之中 ；

The mathematical model of inverted pendulum system is built, and a controller is designed based on the pole placement method with full state feedback to make the inverted pendulum system work stably.
