摘　　要：为实现鱼雷的大范围变速能力,针对热动力鱼雷某型号涡轮发动机系统的非线性和大范围换速和变深中参数变化大的问题,通过对变燃料泵、燃烧室和发动机建模,仿真获得了系统的非线性特性和动态特性以及不同工况下的系统参数,制定了转速闭环控制策略,采用变参数PID控制算法,完成了涡轮发动机转速的闭环控制仿真。仿真结果表明,涡轮发动机的转速闭环控制性能良好。To realize speed variation of a torpedo in a wide range, the nonlinearity and the remarkable variation of pa-rameters due to the speed and depth variations in wide range are considered for a certain type of turbine engine system of thermal propulsion torpedo. The models of fuel-variable pump, combustion chamber and engine are established to obtain the nonlinear and dynamic characteristics of the system as well as the system parameters in different conditions. Further, a closed-loop control strategy of rotary velocity is drawn up, and the proportion-integral-derivative（PID） control algorithm with variable parameters is adopted to implement rotary velocity control simulation of the turbine engine. Simulation results indicate good performance of the closed-loop control of turbine engine rotary velocity.
