摘要
论文针对PCR基因扩增仪对温度的要求提出了与其适应的算法—模糊自整定PID算法。首先给出了PCR反应的各个阶段对温度的响应速度及精度的要求。然后通过对系统建模仿真,分别得到变换隶属函数前后模糊PID与模糊自整定PID的两条曲线。最后给出了模糊PID与模糊自整定PID的对比关系。发现同模糊PID相比模糊自整定PID的响应速度快,超调量小,使系统更稳定。
Based on the temperature requirements of PCR gene amplification instrument and its adaptive algorithm,putting forward a fuzzy self-tuning PID algorithm.First,the polymerase chain reaction（PCR） of each stage of temperature response speed and precision requirements are given.Then through the system modeling simulation,the two curves are repectively got before and after the transformation membership about function of fuzzy PID and fuzzy self-tuning PID.Finally give the contrast relationship of fuzzy PID and fuzzy self-tuning PID.Found that compared with fuzzy PID,fuzzy self-tuning PID has fast response,small overshoot,and makes the system more stable.
