Fuzzy logic-based adaptive control scheme for magnetic levitation systems
The design of an adaptive control scheme (CS) for the control of a sphere in a magnetic levitation system laboratory equipment is presented in this paper. The linearized mathematical model of the process is stabilized by a state feedback controller. The zero steady-state control error is ensured by designing a proportional-integral-derivative controller. A fuzzy proportional-integral-derivative gainscheduling controller is designed to ensure the switching between the linear proportional-integral-derivative controllers. Some simulation results are presented to validate the proposed control structures.
