摘　　要：基于压强调节阀控制的动力系统换速问题是决定某水下航行器(如鱼雷)热动力系统安全性的最重要的问题。文中从系统对调节器功能的要求出发,提出了速度控制方案,合理建立了系统的机理模型,讨论了比例传递函数的实现,研究了关键结构参数对系统性能的影响,并进一步进行了系统优化,对系统动态过程进行了仿真,仿真结果与试验结果相吻合,所设计的压强调节器,方案可行合理,满足所要求的主要技术指标。The varying work condition is the most important problem to the underwater thermal engine system which controlled by pressure regulator. Based on the requirements to regulator function of overall system, the velocity control scheme is provided, the actualization of transfer function is analyzed, by evaluated the influence of key characteristic parameters to the system performance, the paper makes optimal design for the system, the results of simulation and experiments show that the design of pressure regulator is feasible, the velocity control scheme is reasonable. The regulator can meet the main technologic specifications well.
