Abstract: Aiming at the leak detection of PID control method based on volume compensation is only applicable to sampling inspection or small batch, and does not apply to mass product testing, PID control method was studied on the volume to compensate the leak detection platform, improved on the basis of that, a new control methodImproved Genetic PID control volume compensation method was proposed. Finally, detecting system control software was designed by using the algorithm of PID control method and improved genetic PID control method as the volumecompensation control. Experiments were done with the software. The results indicate that relative to PID control method, improved genetic PID control volume compensation method while maintaining other performance indicators greatly improves the system detection efficiency.

 

Key words: volume compensation; improved genetic PID control; leak detection
