生化分析仪主要用于检测人体的体液在临床状态下的多项生化指标的变化，采用的技术是光、电和机来进行临床检测，因此对于其的恒温控制要求非常高，但一般的PID控制只是单一地复制并模拟PID控制器的功能，因此在有些状况下并不具有良好的控制效果。针对这一问题，本文提出了基于混合蛙跳优化PID算法的生化分析仪恒温控制模型，模仿青蛙群体觅食时，用群族分类来表示思想传递的过程，再利用局部搜索的功能，使得局部个体间信息的传递和全局整体的信息传递有机结合，这种方式就叫做混合策略。通过仿真测试结果表明，常规PID算法模型和本文所提出的混合蛙跳优化PID算法模型控制性能上没有太大的提高，但是混合蛙跳优化PID算法在控制时候的稳定能力上有较大的提高，并且其自我适应的能力和抗干扰的能力明显增强。

Biochemical analyzer is a professional instrument in detecting several biochemical indexes of body fluid in clinic, with light, electricity and machines for detection. It has an extremely high standard of its constant temperature control, but general PID control is only a simple reproduction of the function of PID controller, which cannot produce the effect the biochemical analyzer requires. In view of this problem, this paper proposes a PID algorithm optimized by mixed leapfrog for the constant temperature control of biochemical analyzer, simulates the foraging of frog population that transfer the thought through population classification and combine the locally mutual transfer and global information exchange through local search, and thus finally realizes the thought exchange with mixed strategy. Simulation tests show that compared with traditional PID algorithms, our proposed algorithm based on mixed leapfrog has a great improvement in stability, self-adaption and anti-interference.
