Fuzzy Control of a Magnetic Levitation System for a Linear Drive and Comparison with a State Control
نویسندگان
چکیده
In this paper a fuzzy levitation controller for a one degree of freedom maglev application is designed and its performance is compared with the performance of a state controller. The comparison is based on both simulation and measurement results. The maglev application is a levitation/propulsion head of an autonomous transportation vehicle with a nominal air gap value of 2.5 mm. First a nonlinear model of the system is presented. After a short description of the state controller the design of the fuzzy controller is specified. Simulations with noisy signals indicate the noise sensitiveness of the fuzzy controller as a major drawback. Measurements acknowledge this fact. It is shown that for this application the state controller is a better choice because of its robust performance.
