AI Technical Summary

Problems solved by technology

The existing commercial products of pneumatic servo controllers can achieve high positioning control accuracy, but their continuous trajectory tracking performance is weak; most of the pneumatic servo controllers studied by domestic and foreign scholars are designed for hardware circuits, and the core algorithm of the controller There is no breakthrough, and the control effect is very general; and because of the complexity of establishing an accurate pneumatic servo system model, most of the designed servo control strategies are simple and have poor control effects, high controller costs, low integration, and single communication methods , low degree of network intelligence, poor topology, and inconvenient secondary development, etc., so the pneumatic servo controller has a lot of room for improvement
