摘要
飞行器自毁系统是飞行器的重要组成部分,它的可靠性和稳定性是飞行器可靠工作的基础。分析飞行器自毁系统工作原理,采用复杂可编程逻辑器件(CPLD)实现了飞行器自毁系统设计,结合CPLD的特点,提出一种基于改进型有限状态机的飞行器自毁系统时序控制的设计方法,并在CPLD中予以实现。仿真及实验表明,基于有限状态机的飞行器自毁系统定时精度达到纳秒级,可以有效地控制自毁信号输出并消除毛刺现象,很好地满足系统性能要求。该方法具有结构简单紧凑、成本低、可靠性高、精度高等优点。
Aerocraft self- destruction system is a very important part of an aerocraft system, and its reliability and stability are the basis of a reliable aerocraft system. The principle of operation of the aerocraft selfdestruction system is analysed. An approach to design the sequential control of aerocraft self - destruction system based on modified FSM(Finite State Machine) combining the characteristics of CPLD(Complex Programmable Logic Device)is presented and it is realized in CPLD. The simulations and experimental test reveal that the aerocraft self- destruction system precision is in ns- level,and FSM can control the output of the self - destruction signal and eliminate the burr effectively. It proves that the approach could meet the system performance demands well. The system has the merits of simple and compact structure, low cost, high reliability and high precision.
