摘要
数字PID控制在生产过程中是一种最普遍采用的控制方法,在机电、冶金、机械、化工等行业中获得了广泛的应用,但对于复杂系统和难控系统来讲,PID在控制精度、抗干扰性等方面都存在不足。运用模糊数学的基本理论和方法,把规则的条件、操作用模糊集表示,并把这些模糊控制规则以及有关信息作为知识存入计算机知识库中,然后计算机根据控制系统的实际相应情况,运用模糊推理,可自动实现对PID参数的最佳调整,这就是模糊自适应PID控制。
he computer becomes the replacement of analog adjustor being a computer control system since the computer comes into the field of control. The digital PID control is the common control method in the process of manufacture. It has extensive used in the field of machine, metallurgy, chemical etc. But it has shortage in the aspect of control precision and capability of anti - jamming. It has been discussed in this paper that fuzzy control use in the PID control also contrast with the ordinary PID control.
