航空发动机性能退化缓解控制技术

Performance deterioration mitigation control of aero-engine

开展了航空发动机性能退化缓解控制技术的相关研究.性能退化缓解控制通过内环控制转速,外环控制推力,实现了对航空发动机的控制.该控制方式既有传统控制方式的优点,又能像直接推力控制那样实现对推力的直接控制,达到提高发动机控制自主性的目的.为了验证性能退化缓解控制的有效性,以某型双轴混排涡扇发动机为对象进行了控制系统设计及仿真验证.仿真结果表明了性能退化缓解控制技术的有效性和可行性.

The research on PDMC（performance deterioration mitigation control） of intelligent engine was performed.The PDMC consists of both loops,for example,the inner loop controls the rotor speed and the outer loop controls the thrust.As a result,it not only inherits the advantage of traditional control system,but also can realize the direct control of thrust as the direct thrust control.Meanwhile,it enhances the autonomous control of aero-engine.To verify the effectiveness of PDMC,simulations on a two-spool-mixed-flow-turbofan engine were performed.The simulation results show the efficacy and feasibility of PDMC technology.
