摘　　要：针对低浓度瓦斯发电过程中低浓度瓦斯输送系统存在强耦合、延迟、干扰等问题,提出了基于模糊自适应PID控制算法的安全输送方案,通过鼓入空气对瓦斯浓度和压力进行实时调节,最终实现瓦斯浓度和压强保持恒定不变。实践证明,该系统实时性好、控制精度高,很好地解决了低浓度瓦斯的安全输送问题。Aiming at the problems of low concentration gas transportation system in gas power generation,such as strong coupling,delay,interference,the paper proposed a safe transportation scheme based on adaptive fuzzy PID control algorithm,realizing real- time adjustment of gas concentration and pressure through injecting air into the mixed gas,maintaining the constancy of gas concentration and pressure. And practice verified that,the system has favorable real-time property,high control precision,and realized safe transportation of low concentration gas.
