摘　　要：针对航空发动机高、低压转速和压比控制回路,研究中考虑执行机构动态的高阶开环传递函数,根据推广到时滞系统的棱边定理,采用频域方法设计有参数不确定性的非精确模型的鲁棒PI控制器;并利用不确定范围内的发动机非线性模型构成的棱边系统和不确定系统族,验证了鲁棒控制器作用下的系统性能。仿真结果表明,该频域设计方法能使闭环系统的性能指标和鲁棒性均达标。For the aero-engine high and low pressure rotor speed control loops and pressure ratio controlloop, considering dynamic high order open loop transfer function of execute mechanism, the frequency do?main method of designing the robust PI controller for the non-exact models with parameter uncertaintieswas researched, which based on the edge theorem extended to time-delay systems; then the edge systemsand the uncertain system family contained the engine nonlinear model that in the range of uncertainty wereused to validate the system performance under the robust controller. Simulation results demonstrate that thedesign method satisfies performance indices and robustness of closed loop system.
