摘要
讨论了模糊推理算法在燃气热水器中的应用,此算法不依赖于被控对象精确的数学模型,主要是通过控制燃气流量即控制燃气蝶阀来达到恒定温度的目的。从理论上阐述了燃气热水器的工作流程,以及采用的最新节能气阀——蝶阀的特点;着重讨论了模糊控制器的设计过程、原理及参数的整定方法,以及分离式PID模块的启用规则。成功案例的结果表明,该系统控制精度高,稳定性良好,气阀跟踪及时快速,尤其是在水流量一定而改变设定温度的情况下恒温效果良好,充分验证了该设计的有效性与实用价值。
Basing on Fuzzy reasoning technology, this paper introduces the work flow of Gas water heater, and the trait of papilionaceous valve. It also describes the designing process of Fuzzy controller, its theory and the method of making parameter. The experiment results show that this temperature control system has better characteristics such as high- precision, good dynamic performance, excellent control effect, and so on. The design shows its validity and practicability.
