【Abstract】 The liquid level control system based on DeviceNet is built up. The fuzzy-PID controller is designed and realized by making use of the Rockwell Automation’s equipment and software. The result shows that this control algorithm can have not only the advantage of PID algorithm and fuzzy algorithm but also the strong robustness. The fuzzy-PID controller can adapt the change of the parameter in network run, which makes the realization of the engineer easy, and the solution of liquid level control based on network is provided.更多还原
