ABSTRACT
The control problem of inverted pendulum is recognized the typical control issues in the control theory. In real life, it can be seen as the image that Acrobatics performances, and the physical mechanism is closely related to the stability of control system, it profoundly reveals a basic phenomenon of the nature, that is a natural instability of the object through The intuitive, qualitative that means of control and then it Can have good stability. The study and realization of Inverted pendulum control not only have profound theoretical significance but also have important engineering background. Therefore, the inverted pendulum be able to provide an effective device to validate its control strategy and the feasibility and to test the effectiveness of control law and real-time. It is a widely used physical model. The control methods and techniques of inverted pendulum will have broad prospects for the development and utilization in semiconductor processing and precision instruments, robot technology, the control system of intercept missiles, aircraft and other aspects of docking control technology.
This topic for Simple Inverted Pendulum System raise the ARM-based control scheme, simple inverted pendulum and its vector of movement model is plex non-linear model. This subject obtains the theory model of the car and the swing link part of inver
