Stabilization of an inverted flexible pendulum by fuzzy control

Speedup of controlled system and lighting of material are requested in many fields of industry e.g. a manipulator and the universe structure. It draws attention to suppressing vibration of a flexible structure. Fuzzy control is suitable for nonlinear systems like an inverted pendulum. An inverted flexible pendulum is a more unstable system. Fuzzy rules become complex, since the member of the state variables is increased. Then we study a dimensional reduction of variables by considering the new state variables. We consider the control of position because the length of the rail was a limit. We show some results of experiments.
