In order to realize the fast response control for turboshaft engine with variable rotor speed, a dynamic inversion (DI) control method based on state variable model of turboshaft engine is proposed. Meanwhile, in order to expand the application of dynamic inversion controller, the linear parameter varying (LPV) model of turboshaft engine is applied, which constitutes the LPV/DI controller together. The simulation results shows that compared with the conventional PID controller, the LPV/DI controller can effectively reduce the overshoot/droop of the power turbine speed to less than 1% under different flight conditions. The control effect is remarkable and the robust performance is superior.

基于状态变量模型的旋翼综合直升机/发动机系统逆变控制研究

为了实现转子转速可变的涡轮轴发动机的快速响应控制，提出了一种基于涡轮轴发动机状态变量模型的动态逆（DI）控制方法。同时，为了扩展动态逆变器控制器的应用，采用了涡轮轴发动机的线性参数变化（LPV）模型，该模型共同构成了LPV / DI控制器。仿真结果表明，与传统的PID控制器相比，LPV / DI控制器可以在不同的飞行条件下有效地将动力涡轮转速的过冲/下降控制在1％以下。控制效果显着，鲁棒性能优越。
