摘　　要：针对温室环境系统常规控制方法难以取得理想的控制效果的问题,采用模糊从之方法对该问题进行研究。提出了将传统的模糊控制系统分解为控制器和模糊推理器新控制思路,一般控制器是完成系统执行机构的动态性能的优化,模糊推理器完成被控对象的测量信号与控制信号的转换。该方法简化了控制系统的设计和实现,又充分利用了模糊推理器和传统控制方法的优点,采用这种方法设计的温室环境下多变量模糊控制系统,具有消除系统的稳态误差的作用,提高了模糊控制器的控制精度。本系统经仿真,达到了控制要求。In view of the problem that common control methods can＇t achieve the ideal effect of controlling, a fuzzy method is used to study this problem. Thus a new control method is put forward, which divides into two parts： common controller and fuzzy inferior. The common controller responses for the dynamic performance of target system, while the fuzzy inferior completes the conversion of measured signal to control signal of the controlled object. The method simplifies the design and realization of the control system, and meanwhile, it takes full advantage of fuzzy inferior and common control method. Therefore, the fuzzy control multi-variable system using this design method in greenhouse has the function of eliminating the static error and promotes the control orecision of the svstem The system has been simulated and can meet the control requirements.
