摘要
根据某型涡喷发动机不同飞行条件、不同工作状态设计了一组双变量LQ/LTR控制器,同时利用一个神经网络对这组控制器的控制参数进行拟合,以使发动机在全飞行包线内各工作状态都有良好的控制性能。仿真结果表明,在整个飞行包线内,控制系统不但有良好的鲁棒性,而且调节性能良好,能满足发动机控制的要求。
Design of LQG/LTR multivariable feedback controller was discussed in the paper. A group of BIBO (Binary In and Binary Out) LQG/LTR controller was designed based on various operating points at a typical aeroengine flight condition. In order to meet the control requiements at those operating points, a nerve network was used to approximate the control parameters of the LQG/LTR controller. The simulated results have showed that the control system is robust and the regulating process is also good.
