| Abstract: | We design a siding mode controller and a dynamic integral siding mode controller controlling the levitation gaps.The dynamic integral siding mode controller can keep the stability of levitation system and effectively decrease chatting of siding mode controller.The stimulating result shows,compared with these two kinds of controllers,dynamic integral siding mode controller has powerful ability of suppressing disturbance and high rigidity.It can achieve steady levitation. |
