摘要
本文以特定的性能要求为准则,拟定了较为合理的大流量安全阀动态系统结构.在此基础上,利用功率键合图方法建立了阀系统动态数学模型,并以控制论中的ITAE误差指标作为目标函数,对阀系统动态参数进行了优化。
A rational dynamic system construction of a large flow safety valve was designed on the basis of the specific performance in the paper. Then a dynamic mathematical model of the system was built with the method of a power-bond graph. And the dynamic parameters of the valve system was optimized with the ITAE in cybernetics as objective function.
