Fuzzy Adaptive Integral Sliding Mode Control of Suspension Altitude for Single Maglev Guiding System in Linear Elevator

The fuzzy adaptive integral sliding mode control is used, take advantage of sliding mode switching surface weaken the steady-state error and improve robust performance and the precision of steady-state of single maglev guiding system. the output of fuzzy adaptive controller is used to replace the output of switch control for the chattering problem of sliding mode control, and the adaptive control is introduced to estimate and adjust the fuzzy and clear gravity center value. Simulation results show that system achieves good performance with strong robustness.
