以冲压发动机为动力的飞行/推进综合控制

Integrated flight-propulsion control for ramjet vehicle

对以冲压发动机为动力的超声速飞行器进行了巡航状态下的纵向飞行/推进综合控制研究。建立了考虑系统干扰和传感器噪声的系统模型。为消除静差,使用积分型LQG方法进行了飞行/推进综合控制。仿真结果表明,所设计的飞行/推进综合控制器抑制了高度和速度通道之间的耦合,具有一定的抗噪声干扰能力。

Integrated flight-propulsion control (IFPC) in cruise mode was studied for the supersonic vehicle with ramjet. The longitudinal flight and propulsion model was built with system disturbance and sensors noise. An integral LQG control was adopted to design control law. It is shown from the simulation results that the controller designed restrains the channel coupling of the altitude and velocity, and has certain capacity to resist noise disturbance.
