switching surface meaning in English

开关曲面

The states of the closed loop system moved in the sliding mode band of the time - varying sliding surface globally . reaching mode is eliminated and robustness of the closed - loop system is enhanced . the sign function of the switching surface function is replaced by a saturate function to reduce the chattering
该控制方法使得闭环系统对于任意初始状态都处于滑动模态区内，然后通过结合旋转和平移滑模面的方法，使随后任何时刻的系统状态都处于滑动模态区内。
The system selects switching surface according to the approach of variable structure control . based on the control rules to design the variable structure controllers , the inner loop and the outer loop form a complete vsc control loop . the control system has switching surface and the system brings sliding along fixed desired trajectories
根据滑模变结构控制方法选择切换面，根据控制律，设计变结构控制器，使内环和外环合成为一个vsc控制器，系统的控制有切换，而且在切换面上系统将会沿着固定的轨迹产生滑动运动。
