摘要

摘要: 由于基于流量的单变量控制涡轮发动机动力系统运行经济性较差, 提出了基于喷嘴数开环控制和变量燃料泵流量闭环控制的方法, 进而实现涡轮发动机的无级变速。闭环控制采用改进的自适应算法, 使得双变量控制方法简单实用, 适用于无级变速反舰兼反潜的重型水下航行器, 提高了系统运行效率和平稳性。仿真结果表明, 水下航行器涡轮机动力系统采用喷嘴数开环调节和变量燃料泵流量闭环调节的双变量方式, 系统的压力波动和转速波动小, 同时较采用单一流量调节的系统燃料秒耗量降低了28%, 涡轮叶片前的温度也可降低约230 K。

Abstract: For the low energy transformation efficiency of the turbine system controlled by single variable flow rate, a bi-variable control method combining open-loop control of working nozzle number and closed-loop control of variable flow rate of fuel pump is proposed to realize stepless speed control of turbine engine. An improved adaptive control algorithm is used for the closed-loop control. This bi-variable control method is simple and suitable for anti-ship and anti-submarine autonomous underwater vehicles, and can make the turbine system work with high efficiency and stabil-ity. Simulation result indicates that the turbine system with the bi-variable control achieves lower fluctuation in both pressure and speed, and obtains a 28% reduction in fuel consumption of the system and a 230 K decrease in temperature of foreside of turbine vane, compared with the turbine system with single variable control.
