In this paper, an optimal control problem for aero-engines based on a switched linear parameter varying (LPV) model is solved. Firstly, according to the change of external flight conditions, a switched LPV model with different altitudes and Mach numbers is established for aero-engines. Then, since the optimal control of the parameter-dependent switched system cannot be dealt with by traditional methods, we thus propose an optimal control method for the switched LPV system, which includes solving the optimal continuous inputs and the optimal switching instants. Finally, simulations and a hardware in-the-loop test of an aero-engine control system are presented to verify the effectiveness and superiority for the proposed optimal control method.

基于切换LPV模型的航空发动机系统优化控制

在本文中，解决了基于切换线性参数变化 (LPV) 模型的航空发动机优化控制问题。首先，根据外部飞行条件的变化，建立了航空发动机不同高度和马赫数的切换式LPV模型。然后，由于参数依赖切换系统的最优控制无法通过传统方法处理，因此我们提出了一种切换LPV系统的最优控制方法，包括求解最优连续输入和最优切换时刻。最后，通过对某航空发动机控制系统进行仿真和硬件在环测试，验证了所提出的最优控制方法的有效性和优越性。
