摘　　要：针对生物质气化发电技术中气体燃料成分的差异对生物质气体燃料发动机的输出功率造成不稳定影响的问题,文章提出一种控制系统,给出了系统的控制方案,根据生物质气体燃料发动机的原理,建立数学模型,并完成了控制系统的仿真研究。结果表明,该控制系统能够有效改善生物质气体燃料发动机的输出功率,具有较好的动态性能和抗干扰性,满足控制要求。In biomass gasification and power generation technology,the component differences of fuel gas cause a lot of impact on the biogas engine,one of which is the biogas engine output power is not stable. To solve this problem,this paper puted forward a kind of control system,the control scheme of the system was given. According to the principle of biogas engine,the mathematical model was established,and the simulation study of control system was completed. The results showed that the control system can effectively improve the output power of the system. The control system has the preferable dynamic performance and interference rejection,and it was satisfied with the control demands.
