| Abstract: | The variable structure control(VSC) was adopted to expand the bandwidth of the simulation table in this paper.The control law of VSC was given through model transform according to the numerical model of the control object.The dither was reduced by sign function continuum.The results of the numerical simulation and close loop simulation showed that the control system of the simulation table that adopted the VSC controller had characteristics of fast response and good robustness. |

| Keywords: | Simulation table Variable structure control Sliding mode Switching surface Dither Robustness |
