摘　　要：为探讨执行机构对航空发动机控制系统设计的影响,采用多变量H∞控制器设计方法进行了某型航空发动机中间状态控制系统的设计,利用数字仿真平台进行了有无执行机构时控制系统的对比仿真。结果表明,执行机构的加入能帮助控制器对控制量能量进行约束,同时,在控制量增大的方向上,控制系统具有很大的鲁棒稳定和鲁棒性能范围。The influence of actuators on the dynamic performance of aeroengine control systems, and the interme diatestate control systems design problem for certain model of aeroengine based on multivariable H∞ controller design theory was investigated. The comparative simulation results were provided on the platform of numerical simulation for control systems with and without actuators, which demonstrate that actuators can help controller constrain control energy and in the incremental direction of control signal, system considered possesses strong robust stability and performance.
