摘　　要：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。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.
