摘要
由于涡轮机对于变工况的敏感程度远远超过活塞机,随着工况的不同,特别是工况变动范围较大时,发动机表现出非线性特征,为发动机功率控制带来困难,因此,有必要采用数字电子控制器对涡轮机动力系统综合控制进行研究。利用发动机转速测量信号解除了转速对被控推进剂流量的耦合作用,利用航深信号补偿了发动机转速增益的变化,合理配置控制参数,采用变参数PID算法实现了系统的无静差控制,同时使控制对象不发生超调。仿真结果表明,该方法能够很快完成发动机的换速且整个过程流量及转速没有超调。
Because torpedo turbine engine is more sensitive than torpedo piston engine to the variable working conditions, the turbine engine appears nonlinear behavior when the working conditions change, and the situation becomes worse when the working conditions change in large-scale, leading to difficult power control of the torpedo turbine engine. Therefore, a digital electronic controller of the turbine engine system is proposed in this paper, where a rotation speed signal of the torpedo turbine engine is used to uncouple the effect of rotation speed on controlled fuel flux, and a depth signal is adopted to compensate the variation gain of rotation speed. A variable-parameter proportional integral differential （PID） control algorithm is applied to achieve zero static state error control of the torpedo turbine engine rotation speed without over-adjusting the controlled objects. Simulation resuhs show that the variable-parameter PID control algorithm makes the torpedo turbine engine speed change quickly without overadjusting fuel flux and rotation speed in the whole process.
