摘　　要：天然气管道出口压力控制属于典型非线性、时变不确定性、易受干扰的系统,常规PID控制就很难达到满意控制效果,因此需充分利用智能PID控制方法来提高供气压力稳定性。本文以输配站民用管线天然气出口压力控制为例,采用模糊参数自整定PID控制做为输配站天然气管道出口压力控制策略,建立天然气管道系统数学模型,进行天然气压力控制系统仿真,研究模糊参数自整定PID控制器在输配站天然气调压方面的应用,以解决供气稳定性的难题。The outlet pressure control of gas pipeline is a typical nonlinear, time-varying, vulnerable system, which is hardly achieved by the conventional PID control. Therefore, the smart PID control is used to improve the stability of gas supply pressure. A mathematical model of gas pipeline is established by fuzzy parameter self-tuning PID control to simulate gas pressure control system with the example of the outlet pressure control on civil pipeline at transferring and distribution station to solve the stability in gas supply.
