摘要
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 stability. 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.关键词
