基于容积补偿的气体泄漏检测遗传PID控制研究

Gas leak detection based on volume compensation genetic PID control

针对基于容积补偿的泄漏检测PID控制方法只适用于抽样检测或小批量检测而不适用于大批量产品检测的问题,在容积补偿泄漏检测平台上对PID控制方法进行了分析研究,在其基础上进行了改进,提出了一种新的控制方法改进的遗传PID控制容积补偿法。最后分别采用PID控制方法与改进的遗传PID控制方法作为容积补偿控制算法,设计了检测系统的控制软件,并进行了实验。研究结果表明,相对于PID控制方法,改进的遗传PID控制容积补偿法在保持其他性能指标的同时大大提高了系统检测效率。

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.
