基于CPLD的某型发动机控制器飞行前检查系统的设计

传统的模拟式电子控制系统具有元件漂移大、抗干扰能力差、可靠性差等问题。为了提高某型航空发动机综合电子控制器的控制精度,采用CPLD技术研制了发动机综合电子调节器飞行前检查系统,并给出了具体的设计过程。结果表明：所设计的系统可以很好的替代模拟式控制器的飞行前检查系统,可以更有效的对该控制器的状态进行预先检查,并且具有精度高、可靠性高、受环境影响小等优点,应用前景广泛。

A Design of Some Engine Controller Pre-fly Examination System Based on CPLD

The traditional analog electronic control system has the problem of wide drift rating, bad anti-jamming ability and unreliability. A digital electronic flight control system using for pre-fly examination system based on CPLD technology is designed, which aims at improving the control precision of the electric control system in some flight engine. The design progress is expatiated in the paper. The result shows that the designed system can take the place of pre-fly examination system of the analog control system. It makes the examination of control system more efficient and has the advantage of high precision, high reliability and extensive applicability. The system can be widely used in practice.
