摘要：

构建了调节阀煤气稳压系统,建立了稳压系统的数学模型,并设计了稳压系统的模糊PID(proportion integration differentiation)控制器。在此基础上,根据所建立的数学模型,分别对常规PID控制和模糊PID控制下的稳压系统性能进行了仿真分析。结果表明模糊PID控制器能明显提高稳压系统的控制品质。

Abstract:

A mixed-gas stabilized-pressure system based on a control valve was designed. The model of the mixedgas stabilizedpressure system was built and the fuzzy PID controller for the stabilizedpressure system was designed. Based on the model, the control performance simulation analyses of the stabilizedpressure system with the traditional PID controller and the fuzzy PID controller were carried out. Simulation results showed that the fuzzy PID controller can provide better performance than the traditional PID controller.

Key words: control valve, stabilized pressure technology, fuzzy PID, electro-hydraulic system
