摘要
某型发动机的防喘控制系统曾多次出现故障,影响发动机正常工作。为了更好发挥发动机性能,有必要对防喘控制系统进行分析,了解其特性。对某型发动机的防喘控制装置的结构及功能进行了分析。具体说明了防喘控制装置模型的建立方式。针对建立的模型对于防喘控制系统特性进行了仿真,得出了真实防喘控制系统实现的控制规律,验证了模型的稳态及动态特性与真实的防喘控制系统一致,确定了模型的可靠性。
Fault often occurred for a certain engine’s anti-surging control system,affecting the normal operation of the engine. In order to better utilize the engine’ s performance,it is necessary to analyze the anti-surging control system andlearn about its characteristics. Firstly,the structure and function of the anti-surging control systemis analyzed. Then,the establishment of the anti-surge control system model is specifically described. Finally,the characteristics of the anti-surging control system are studied through simulation,and the control law of the real system is obtained. It is verified that the steady state and dynamic characteristics of the model are consistent with the real system. So,the model is reliable.
