航空发动机伺服作动主备异构控制研究
Main-Backup Heterogeneous Control of Aero Engine Servo Actuator
摘要
Abstract
In order to improve the reliability of servo control tasks such as aeroengine fuel metering,guide vane and nozzle throat area,avoid the failure of servo control caused by co-mode failure of the dual residual electro-hydraulic conversion devices,through analyzing the control requirements of different servo actuator,dissimilar redundancy control devices are designed for these different servo actuator control requirements.Dual-residual jet pipe electro-hydraulic servo valve(EHSV)with strong anti-pollution capability is adopt as the main control electro-hydraulic device,meanwhile the heterogeneous high-speed solenoid valve is added as backup device.PID controllers are designed for different single-loop and double-loop position closing control loops of servo ac-tuator,and the semi-physical simulation verification of the main-backup control performance of servo loop and the bench test of the main-back switch are carried out.The test results show that the designed main-backup heterogeneous control devices can meet the operational requirements of aeroengine,and can effectively avoid the occurrence of the co-mode failure of the electro-hydraulic conversion devices,thereby improving the securi-ty of the servo control and the system survival.关键词
