| 摘要: |
| 主要研究了航空发动机加力过渡态控制的新方法。在不改变原有发动机控制结构的基础上,提出了一种增广LQR法(Augmented Linear Quadratic regulator-ALQR)综合ADRC(Active Disturbance Rejection Control)干扰补偿控制的算法(简称ALQR+ADRC),该算法除了有原ALQR控制所具备的强的消除静差能力之外,还兼具AD-RC优良的干扰补偿能力。通过模拟快速进入/退出发动机加力过渡态过程,验证了该算法具有理想的控制效果,能够较好地协调加力燃油供给和喷口开张,在整个过渡态过程中对核心机工作有较小的影响。 |

| Abstract: |
| A new method for Aero-engines afterburning transition state control problem is studied. A new hybrid control structure which is an Augmented Linear Quadratic regulator combined with ADRC,is proposed,keeping the formal control structure for the engine unchanged. The new control system not only has the excellent static error elimination ability but also the ADRC strong disturbance compensation ability. The better transition state control effect is verified by the engine transition state simulation of entering into and withdrawing from the afterburning state,and the core-engine work is slightly influenced due to the afterburner fuel and nozzle throat area coordinate operation in the process. |
