Design and Implementation of Miniaturized Flight Control Computer Based on FPGA+DSP

Abstract

With the great changes in the international situation today, whether it is the war in Afghanistan or the war between Russia and Ukraine, all of them reflect the importance of military strength to a country, and the research of precision guided weapons is a key part of improving military strength. With the rapid development of science and technology, as the core component of guided weapons, the miniaturized flight control computer system should keep pace with the times and have better performance and better reliability. In this paper, a flight control computer with high performance and strong versatility is designed based on the flight test of a certain type of missile. The flight control computer based on FPGA and DSP introduced in this paper makes full use of the respective advantages of the two processors, and has the characteristics of strong real- time processing capability, small size, light weight and low power. The computer realize the function of serial communication, discrete input and output, analog input and output, double-ended RAM storage, etc. After many flight tests, it has been shown that the system has good reliability and stability, and has certain engineering application value.
