This invention discloses a sliding mode control method for wastewater treatment processes based on predetermined time performance, belonging to the field of wastewater treatment and nonlinear control technology. This invention is the first to combine second-order integral sliding mode control with a second-order command filter and apply it to the control system of a wastewater treatment plant (WWTP). It considers the requirement that the control coefficient must be greater than 0, and the control effect is superior to existing results. To ensure the timely operation of the wastewater treatment plant, predetermined time performance is used to keep the overall control performance within a specified range and achieve faster convergence. An improved integral sliding surface is constructed, and a novel adaptive controller is designed, achieving stable control of the wastewater treatment plant under three different weather conditions.

The utility model discloses a turnover device for processing a wine bottle outer packaging box, which relates to the technical field of outer packaging box processing, and comprises a workbench and a packaging paperboard, the top of the workbench is provided with a support, the support is internally provided with a convex sliding chute, the interior of the convex sliding chute is slidably connected with two convex sliding blocks, and the convex sliding blocks are connected with the packaging paperboard. And the bottoms of the two convex sliding blocks are fixedly connected with supporting frames, limiting plates are installed at the bottoms of the supporting frames, and the interiors of the convex sliding grooves are rotationally connected with bidirectional lead screws. The turnover device for processing the outer packaging box of the wine bottle has the beneficial effects that the position of the packaging paperboard is standardized through the movable limiting plate, the suction plate is attached to and adsorbed to the surface of the packaging paperboard under the action of the electrician push rod and the sucking pump, and the packaging paperboard is conveniently and stably driven to turn over along with the rotation of the suction plate, so that the packaging paperboard is prevented from being damaged. And acting force is applied to the surface of the packaging paperboard, paperboard deformation is avoided, the structure is simple, and operation is convenient.
