摘　　要：循环发电工程是以天然气作为燃料,采用燃气-蒸汽联合循环发电技术来发电的工程。在此过程中,由于受到诸多因素影响,送往燃气轮机的气体压力产生无法避免的波动。为解决该问题,设计了天然气稳压系统,建立了系统数学模型,在MATLAB环境下分别对系统进行了PID控制、模糊控制和模糊PID控制的仿真与比较。结果表明,模糊PID控制能明显提高稳压系统对压力扰动的抑制能力和控制品质。Using natural gas as fuel, a cyclic power generation project uses the gassteam hybrid cyclic power generation technology to generate electricity. In the power generation process, the gas pressure that flows to the gas turbine generator is inevitably influenced. To solve the problem, a regulating valve gas stabilizedpressure system is designed. A mathemat ical system model is established, and the traditional PID controller, fuzzy controller and fuzzy PID controller are stimulated and compared with MATLAB. The results show that the fuzzyPID controller can better suppress the pressure perturbation and improve the control of pressure disturbance.
