摘　　要：基于LMI(LinearMatrixInequality,线性矩阵不等式),提出一种航空发动机PI输出反馈控制器设计方法。利用被控对象中控制向量2范数上界的限制,提出了一种改进ILMI(IterativeLMI)算法,用于解决控制受约束的航空发动机PI控制器的一种LMI描述求解问题。以某型双转子涡喷发动机为被控对象,基于LMI进行了PI输出反馈控制器的设计,并分区域在飞行包线进行了航空发动机控制系统仿真验证。结果表明,所得控制器满足预期设计要求,同时具有一定鲁棒性。A LMI (Linear Matrix Inequality)-based method to solve PI output feedback control for aero-engine is presented. Control input is restricted by using the upper bound for its Euclidian 2-norm. An improved ILMI (Iterative LMI) algorithm is proposed to solve the problem of PI output feedback control with constraint on control input for aero-engine. This design method is applied to the control system design of some aero-engine. Simulation results show that the requirement for controller, which has some robustness, is satisfied.
