The authors propose an adaptive robust control approach for the levitation of non-linear maglev vehicle with state constraint. system contains and (possibly) time-varying uncertainty, which is supposed to be bounded. In order prevent undesirable collision, airgap between suspended chassis guideway should restrained in a specified range safety concerns. Furthermore, does not satisfy (global) matching condition. three-step transformation transform interconnected uncertain system. After that, proposed based on transformed system, law constructed emulate total uncertainty. able ensure performance (uniform boundedness uniform ultimate boundedness) vehicle. addition, can confined within range.
