【Abstract】 The influence of actuators on the dynamic performance of aeroengine control systems, and the intermediate state 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.更多还原
