| 摘 要： | 中央空调的耗能问题日益引起了人们的关注.由于其系统存在很大程度的非线性、大滞后和参数时变性,采用传统的PID控制有很大的困难.模糊控制的优点是能够得到较好的动态响应特性,并且无需知道被控对象的数学模型,适应性强,上升时间快,鲁棒性好.但模糊控制受模糊规则有限等级的限制,容易引起误差.设计中采用AT89C58作为控制内核,结合模糊控制和PID算法的优点,提出参数自适应模糊PID算法.实验证明,该系统稳定、快速且其抗干扰能力能够满足变流量控制系统的需要.

| Abstract: | Traditional PID control is hard to use in the great nonlinearity,lag and parameter raritey of central condi-tioner.The fussy-control has the advantage of better dynamic response characteristic,better adaptability,faster rise time and better robust characteristic,and the mathematic model of controlled object is not needed in arithmetic,but it causes error easily because of the limitation by fussy-control grade.The fussy-PID arithmetic was presented,and AT89C58 was used as control kernel.The experiments show that the system is fast,stable and can satisfy the need of variable-flux equipment. |
