摘　　要：为了解决传统PID控制器控制电冰箱温度所存在的响应速度慢、控制精度不高等问题,本文采用自整定模糊PID控制算法设计了模糊PID控制器,并在MATLAB环境中进行了仿真,与常规PID控制器的性能进行了对比,结果表明模糊自适应PID控制器的响应特性优于传统的PID控制器,响应速度更快,稳态精度更高,超调量更小,提高了电冰箱温度控制系统的性能。最后在ARM芯片上实现模糊控制算法,模糊控制表采用新方法二维矩阵存储,以便方便查询和管理,更好地满足温度调节的实时性。To solve the problems that the traditional PID controller can not satisfy the high response speed and high performance, this paper designes a self - adaptive fnzzy PID controller, and carries on the simulation in the MATLAB environment and compares with the conventional PID controller＇s performance. The result shows that the self - adaptive fuzzy PID controller＇s response is superior to the traditional PID controller,and the response speed is faster and more stable precision. It implementes storage of fuzzy control table on the MPU with a new method of two dimension matrix, to expediently look for and manage, and to meet real time of temperature adjusting.
