基于PLC的模糊自适应PID控制器设计(任务书,开题报告,外文翻译,论文说明书12000字)
摘  要
实际工业生产过程中可能有许多变量、不具备线性特性、时常改变且并不确定等特点，再考虑工程应用中控制的实时性、效率性和经济性等考量因素,使得对数学模型需求极高、时刻以最佳的性能指标为目标且计算方法通常非常繁复的现代控制理论在复杂的工业生产过程中难以发挥作用。使用模糊控制可以不用建立数学模型,很多繁复的情况的可以适应,被认为复杂控制的新方法。
本设计首先凭借数学建模的方法获得双容水箱的模型,设计模糊PID控制器，计算得到模糊规则控制表。用仿真软件Matlab进行仿真。使用西门子组态软件STEP7 MicroWIN在S7-200PLC上实现模糊PID算法。使用监控组态软件WinCC编写界面,实时监控实验。实验结果表明,模糊PID控制效果优越，响应速度块且超调量小，抗干扰性远优于PID控制。

Fuzzy Adaptive PID Controller Based on PLC
Abstract
The actual process of industrial production may have many variables which do not have a linear characteristic, do not change often,and is not determined by other characteristics.Consider ing the real-time control engineering applications, efficiency and economy and other considerations, such a high demand for mathematical models , always with the best performance for the target and the calculation method is usually very complicated modern control theory is difficult to play a role in complex industrial processes.
Fuzzy Control can be used without a mathematical model.It can also adapt tomany complex cases.As a result,it is considered to the new complex method of control .
The design is first obtained by the method of mathematical modeling with double - tank model.Then design the fuzzy PID controller and calculate the fuzzy control rules table. The process of simulation is realized by using simulation software Matlab.
Fuzzy PID algorithm is realized in Siemens configuration software STEP7 MicroWIN.
Using the configuration software WINCC to write interface and realize real-time monitoring experiments.
Experimental results show that the fuzzy PID control performance is superior to PID control with faster response and smaller overshoot.
Keywords: Fuzzy PID algorithm; Matlab simulation; S7-200 PLC; STEP7 MicroWIN; WINCC
