1.Electro-hydraulic servo control systems can be classified as valve-controlled and pump- controlled systems. The valve-controlled system has fast response. But, its noise level is high and energy efficiency is low. In the contrast, the pump-controlled system has low noise level and high energy efficiency. Nevertheless, its response is sluggish. 2.The valve-controlled system has an optimal energy efficiency of only about 37%, and the best energy efficiency of the pump-controlled system can reach 90%. Therefore, the pump-controlled folding machine saves a lot of energy compared with valve-controlled folding machine. The results of the invention will help the domestic industry save energy. In the 21st century, the energy issue is an important issue in economic development. Therefore, the research and development achievements of the pump-controlled folding machine can be promoted from domestic to abroad. 3.The response of pump-controlled folding machine is about 90% of that of valve-controlled machine, and it is quite close to valve-controlled folding machine in response. 4. The pump-controlled folding machine uses a coupled adaptive self-organizing sliding mode fuzzy controller. Sliding plane equation reduces two-dimensional system variables into one-dimensional system variables. One-dimensional self-learning mechanism provides the best fuzzy rules in time. The adaptive law adjusts the defuzzification scale factor in time. The coupling controller and regulator improve the coupling effect. Therefore, the synchronization of this machine is better than the traditional valve-controlled folding machine which using a proportional controller. 5. Dual-axis electro-hydraulic servo control folding machine is a typical example of the hydraulic drive system application in the manufacturing industry. It is also a kind of machine tool. The design and development technology of the pump-controlled folding machine can be extended to other machine tools, and even can be extended to all electro-hydraulic servo controlled machines. 6. The successful development of the coupled fuzzy controller reduces the influence of the asymmetrical and structural coupling effects of the dual-axis pump-controlled hydraulic folding machine and improves the control precision of the dual-axis pump-controlled hydraulic folding machine, making the pump-controlled system close to the valve-controlled system. The control accuracy, coupled with the energy-saving effect and low noise of the pump-controlled system, allows the electro-hydraulic servo pump-controlled folding machine to replace the electro-hydraulic servo valve-controlled folding machine. 7. The research and development of electro-hydraulic servo pump-controlled folding machine provides the related software and hardware design technology to domestic folding machine manufacturer about dual-axis pump-controlled electro-hydraulic servo folding machine, which helps to improve domestic production quality and develop energy-saving hydraulic processing machine. 8.
