Introduction
The servo pneumatic proportional valve control system is a widely used automation control system that achieves precise and rapid control of complex mechanical systems through precise control of the action of pneumatic actuating elements.

Design of the servo pneumatic proportional valve control system
The core of the servo pneumatic proportional valve control system lies in the precise control of the pneumatic actuating element, which depends on the precise control of the pneumatic proportional valve. Therefore, the design of the servo pneumatic proportional valve control system needs to start from the selection of the pneumatic proportional valve, the selection of the control strategy, and the system integration.
Selection of pneumatic proportional valves
The selection of pneumatic proportional valves needs to consider multiple factors, including the type of actuating element, the working pressure and flow requirements of the pneumatic system, control accuracy, and the system's requirements for response speed. Generally, the selection of pneumatic proportional valves should follow the following principles: first, ｓｅｌｅｃｔ the appropriate pneumatic actuating element according to the type of actuating element; second, ｓｅｌｅｃｔ the appropriate pneumatic actuating element according to the working pressure and flow requirements of the pneumatic system; finally, ｓｅｌｅｃｔ the appropriate pneumatic proportional valve according to the requirements for control accuracy and response speed.
Selection of control strategies
The selection of control strategies is a key factor in the design of the servo pneumatic proportional valve control system. Common control strategies include PID control, fuzzy control, and neural network control. PID control is the most commonly used control strategy, which achieves precise control of the actuating element by adjusting the opening of the pneumatic proportional valve. Fuzzy control and neural network control are suitable for complex and nonlinear systems, which improve control accuracy and response speed through learning and optimizing control strategies.
System integration
System integration is an important link in the design of the servo pneumatic proportional valve control system. It requires integrating various components such as pneumatic proportional valves, control algorithms, and sensors into a complete control system. During the system integration process, it is necessary to consider the coordination and stability between the components to ensure the stability and reliability of the entire system.
Application of the servo pneumatic proportional valve control system
The servo pneumatic proportional valve control system has a wide range of applications in many fields, including industrial automation, medical equipment, aerospace, and others. In the field of industrial automation, the servo pneumatic proportional valve control system can be used in automatic production lines, robot systems, and so on; in the field of medical equipment, it can be used in surgical robots, rehabilitation robots, and so on; in the field of aerospace, it can be used in the control systems of aircraft and spacecraft.
