Abstract:

Based on the development of a certain type of missile fight test, a new missile-borne computer which has high precision and high universality has been designed. The missile-borne computer with high performance DSP and FPGA as the system framework, through its rich peripheral interface and powerful processing capabilities, combined with the AD5764 conversion module, MAX3490 communication module, the discrete output module with ADUM1401 four channel digital isolator and ULN2801 Darlington tube etc, which has been solved the problem of the complex parallel date processing between the missile-borne computer and other flight control components, while solved the problem of real-time calculation of a variety of control algorithms, also it has the advantages of small volume, light weight, high precision, good real-time characteristic and so on. The missile-borne computer has been passed by many fight experiments, the results show that it has high reliability and stability, while the prospect of application is very extensive.
