Stabilization of an inverted flexible pendulum by fuzzy control

Recently, speedup of controlled system and lighting of material are requested in many fields of industry. A field of the manipulator and the universe structure occurs flexibility with it. It collects attention that suppressing vibration of flexible structure. It is used well as an object which stabilized unstable dynamical system because the construction is simple, and nonlinearity is strong. Fuzzy control is suitable to non-linear system like inverted pendulum. A inverted flexible pendulum is more unstable system. Fuzzy rules became complex, since the member of the state variables increased. Then we studied a dimensional reduction of variables by considering the new state variables. And we should consider the control of position because the length of rail was a limit. We showed some results of experiments.
