某型飞机发动机在转速超过设定值时需要进行切油控制,在飞机上重要度较高。本文提供一种提高控制器可靠性的设计方案,在基本可靠性变化较小的情况下,通过采用双通道检测设计提高产品的抗干扰能力,使控制器的输出更加稳定、可靠,避免误动作发生导致发动机停车事故。该设计适用于飞机发动机控制系统,也适用于需要提高抗干扰能力的控制系统。在航空航天的控制领域,有着较为广泛的应用。 When a certain type of aircraft engine speed exceeds the set value need to cut oil control, the importance of the aircraft is higher. This article provides a design to improve the reliability of the controller design, in the case of small changes in the basic reliability, through the use of dual-channel detection design to improve the anti-interference ability of the product, the controller output more stable, reliable, to avoid malfunction Occurred leading to the engine stop accident. The design is suitable for aircraft engine control system, but also for control systems that need to improve anti-interference ability. In the field of aerospace control, has a more extensive application.
