基于模糊控制技术的中央空调控制器的仿真研究

针对常规模糊控制技术的不足，从模糊控制的本质出发，分析了现有改善模糊控制器性能的方法。在此基础上，提出了一种变论域模糊控制加PID控制器的方案，设计了相应的控制器，并以中央空调系统为控制对象进行了仿真实验。仿真结果表明，该模糊控制比常规模糊控制的超调量小、稳态精度高并且抗干扰性较好，模糊控制器的性能得到了较大的提高，而且简单易行，适合于硬件实现。

Simulating Research on Central Air Conditioner Controller Based on Fuzzy Control Technology

In view of the defects of the fuzzy control technology,and starting from the essence ot fuzzy control,this paper ana- lyzes the existing method on improving the performances of the fuzzy controller.Based on it,we proposed a kind of variable uni- verse fuzzy control method to add the PID controller,and designed the corresponding controller,and carried out simulation ex- periments with air--conditioning system as the controlled object.The simulation result indicated that this fuzzy control had small over--modulation value,high stable--state precision and good anti--jamming performance.Thus,the performance of the fuzzy controller has been much enhanced.Moreover,it's simple and feasible,suitable for hardware realization.
