发动机限制保护器在航空发动机运行过程中对特定的被限制量进行实时监控,在其超出安全范围时实施限制,实现对航空发动机的保护.将自抗扰技术用于限制保护控制器设计,利用自抗扰控制器的扩张观测器,动态估计未知扰动和系统特性,对实际控制量进行反馈补偿,实现超限后的快速保护,提高了发动机的安全性.仿真结果表明:所设计的自抗扰限制保护控制器能将超限偏差有效转化为对主回路指令的修正,综合控制系统响应速度快,达到了限制保护的目的.
The engine limit protector real-time monitors certain limited quantities during the operation of the aero-engine and imposes limits when it exceeds the safety limits to protect the aeroengine. The ADRC technology is used to limit the protection controller design and utilization Self-disturbance controller dilatometer, dynamic estimation of unknown disturbance and system characteristics, the actual control of the amount of feedback compensation to achieve rapid protection after overrun to improve the safety of the engine.The simulation results show that: the design of the resistance The disturbance limit protection controller effectively transforms the overrun deviation into the correction of the main circuit instruction, and the integrated control system responds fast and reaches the goal of limiting the protection.
