在过程控制中，大多数控制变量是需要平滑的位置量，如阀门的开度。为了获得光滑控制，提出了一种光滑全阶滑模控制器。由于该方法将切换项引入到控制的二阶导数中，因此控制是光滑的，其导数是连续的。在船舶锅炉汽包水位控制中进行了试验，结果表明了该方法的有效性。
In process control, most of the control variables are position quantity which needs to be smooth, such as the opening of valve. In order to get smooth control, a smooth full-order sliding mode controller is proposed. Since the switching term in the proposed method is put into the second derivative of control , the control is smooth and its derivative is continuous. The proposed method is tested in drum water level control of the ship boiler, and the results show the effectiveness of the proposed method.
