An Analysis on the Kinetic Model of a Rotary Inverted Pendulum, and Its Intelligent Control

In this paper it is based on a kind of rotary connection structure driven by DC servo motor, a control system model with single support and rotary inverted pendulum can be constituted by means of controlling a rotary arm in rotation angle and alternate motion rate. The principle of control to simplify energy, which is easy to realize, could be obtained through analysis after the system is performed approximation treating. And angle of revolution of the inverted pendulum, rate of change of the angle and its trend pendulated would be controlled as input variable, adopting the fuzzy control approach, the requirements to the system controlling would be realized satisfactorily for oscillation starting of the inverted pendulum, adjusting process of pendulation, balancing and maintaining the stable conditions, through adjusting the rotating arm in speed of revolution, direction of rotation, angular displacement and rate of change for the rotation angle. And feasibility of this control approach has been tested and verified by the relative system exercises.
