研究了线性非匹配不确定系统的滑模控制问题．引入适当的状态变换，将系统分解成两个子系统，根据滑模控制的到达条件，设计了系统的滑模控制器，使得从任意状态出发的不确定系统能在有限的时

间内到达滑动面-Study non-linear sliding mode control of uncertain systems match the problem. The introduction of the appropriate state transformation, the system is divided into two subsystems, according to the sliding mode control of reaching condition, the sliding mode controller design of the system, making starting from any state of uncertain systems in a limited period of time to reach the sliding surface
