Abstract: Considering the uncertainty model of aeroengine, the equivalent certainty system that quadratically stabilizes the plant can be obtained by restricting the H infinity norm of closed loop transform function from the disturbance input to the controlled output. A design method of robust H_∞/PI style controller is given by means of two free parameter in H_∞ state feedback controller subject to the constraints of PI structure. The robust performance is simulated on the SIMULINK environment.

摘要： 针对航空发动机模型的不确定性问题,在二次稳定且由干扰到被控输出的闭环传递函数的H∞范数约束下,可获得等效的确定性系统,将参数化的H∞状态反馈控制器中的2个自由参数用PI结构进行约束,提出了一种鲁棒H∞ PI型控制器的设计方法,在建立的SIMULINK仿真结构平台上进行了鲁棒性能验证。
