To address the issue of modeling uncertainty in sliding mode control (SMC) of the single-point levitation system, which requires large switching gains and leads to chattering, a fuzzy approximation method is employed to estimate the fuzzy switching gain. A fuzzy switching gain based sliding mode controller is designed, and its stability is also proved. The effectiveness of the designed controller is verified through simulations and comparisons.

A fuzzy switching gain based sliding mode controller is designed, and its stability is also proved. The effectiveness of the designed controller is verified through simulations and comparisons.
