涡轮发动机系统的双变量控制

针对推进剂流量单变量控制的涡轮发动机动力系统运行经济性差等缺点,提出了工作喷嘴数目开环控制配合燃料泵排量闭环控制的双变量控制方法,闭环控制部分采用改进的自适应算法.与单变量控制方法比较,系统经济性提高30%以上,涡轮前温度降低250 K以上.仿真结果表明,该双变量控制方法简单实用,适用于多速制反舰兼反潜的重型水下航行器使用,能够兼顾系统运行效率和平稳性.

Bi-variable control for turbine system

Turbine engine system controlled shortcomings such as low energy translation by single variable propellant flow control has some efficiency. This paper puts forward a bi-variable control method, in this method, the open loop controls the number of working nozzles, the closed loop controls the capacity of variable displacement fuel pump. An improved adaptive control algorithm is used for the closed loop control. Comparing bi-variable control to single variable control, the system can get energy translation efficiency more than 30% and turbine forward temperature lower than 250 K. The simulation results show that the bi-variable control method is simple, can make the turbine engine system get high efficiency and work steadily. This method is fit for antiship and anti-submarine autonomous under water vehicle. 5 figs, 6 refs.
