摘要
针对硫化机温度控制中存在的非线性、不确定性和时变性等特点,在常规PID控制的基础上,提出了一种参数自适应模糊PID控制的设计方法。利用模糊控制理论,在线对PID参数进行调整,采用AT89C52单片机作为模糊控制核心,设计了系统的硬件组成及结构,系统软件设计采用面向对象程序,给出了主控制模块的设计流程。结果表明了该控制方式在动态性、稳定性以及鲁棒性方面都有较大提高。
Aimed at the non-linearity,uncertainty and time variation characteristics of vulcanizing machine temperature control,this paper proposed a fuzzy control method with parameter self-adjustable feature on the basis of existing conventional fuzzy method;adjust the PID parameters online by using the fuzzy control theory.By using AT89C52 MCU as the design core of fuzzy control,the hardware composition and structure was designed.Object-oriented program was adapted in the software design and the main control module design flow was presented.The result shows this method is improved in dynamics,stability and robustness.
