Steel Ball System Control Using T-S Type Fuzzy Logic

In this paper the Takagi-Sugeno type fuzzy logic was utilized for the purpose of control of electromagnetically levitated steel ball system. The system is the basis for important systems such as, the modern train which floats along the rails, aerospace shuttles, magnetic bearings and high precision systems. Such systems apart from being nonlinear they are also not stable. Results were obtained using the SIMULINK/MATLAB software and the control system developed for the electromagnetically levitated steel ball system was able to stabilize it with good response.
