摘　　要：介绍了一种以PLC为核心的船用柴油机排气消声器性能试验台控制系统的实现方法,采用了一种简单实用的模糊控制方案.利用一维模糊控制器和解耦控制规则,解决了输入量与输出量的非线性、大滞后、尤其是其深度耦合的问题,并利用汇编语言编写了控制程序.实际运行表明,试验台的温度控制误差范围不大于±5℃,流量控制误差范围为±5%.A method of how to design and implement the PLC control systems on the test bed for the performauce study of marine diesel engine exhaust silencers was introduced. And a simple and useful fuzzy control scheme was presented. Utilizing the single fuzzy logic controllers （SFLC） and the decoupled rules, the nonlinear between the input and the output variables, big delayed and especially deep coupling problems have been successfully solved. We compile control programs with assemble language simultaneously. The practical function shows that the temperature error is in the range of ± 5 degree centigrade and the flow error is in the range of ±5 %.
