摘　　要：针对离散指数趋近率中的带状切换带会带来系统抖振,降低系统的稳态性能这个问题,结合离散变速趋近率,提出了一种离散组合趋近率,并将其应用于一SISO三容水箱中,通过MATLAB仿真实验,验证了组合趋近率的有效性。Aming at the chattering caused by the zonal switching belt of the discreate EXP law,which may decreased the system steady state performance,we proposed a combined reaching law based on the advantage of EXP reaching law and variable reaching law in this text,then put it into a SISO three-tank system,and it was proved effective by Matlab simulation results.

关 键 词：离散滑模 组合趋近率 抖振 液位系统
