Abstract:
This paper is focused at position deviation regulation upon a slider by Fuzzy Sliding Mode Control (FSMC). Five Degrees Of Freedom (DOFs) of position deviation are required to be regulated except for the direction (i.e., X-axis) in which the slider moves forward and backward. At first, the system dynamic model of slider, including load uncertainty and load position uncertainty, is established. Intensive computer simulations are undertaken to verify the validity of proposed control strategy. Finally, a prototype of realistic slider position deviation regulation system is successfully built up. According to the experiments by cooperation of pneumatic and magnetic control, the actual linear position deviations of slider can be regulated within (-40, +40)μm and angular position deviations within (-2, +2)mini-degrees. From the viewpoint of energy consumption, the applied currents to 8 sets of MAs are all below 1A. To sum up, the closed-loop levitation system by cooperation of pneumatic and magnetic control is capable to account for load uncertainty and uncertainty of the standing position of load to be carried.
