【摘要】 基于传递函数矩阵H∞范数的等价原则思想,将非严格正则模型转化为严格正则模型。通过LMI求解方法,在考虑控制能量约束的条件下,对严格正则模型进行静态输出反馈PI控制器设计。提出了一种非严格正则模型静态输出反馈PI控制器求解的算法。以某型双转子涡喷发动机为被控对象,进行静态输出反馈PI控制器的LMI设计,并分区域在飞行包线进行了动静态性能和鲁棒性能仿真验证。更多还原

【Abstract】 According to the physical meaning of the H_∞ norm,a nonstrict proper model is converted into some strict proper model under the equivalence condition of their H_∞ norms.A static output feedback PI controller for the resulting strict proper model is designed on the basis of LMI,and control constraints are taken into consideration in the design process of the controller.An algorithm for solving the static output feedback PI controller is presented.This method is applied to the design procedure of aero-engine controller.The dynamical and static performances of the aero-engine control system are verified at different partitioned regions of flight envelope.更多还原
