Research of real-time simulation system for air-to-air missile's flight control software

The flight control software simulation technology has become the key in the modern numerical air-to-air missile design. And the keystone is how to validate the flight control software. The key techniques were analyzed to implement the real-time simulation system of air-to-air missile`s flight control software. The Windows XP + RTX real-time operating system platform and the debug system of DSP embedded flight control software were realized. The data conversion of double port RAM was adopted. The exterior hardware interrupt harmonized all the function blocks. Based on them, a flight control software simulation system was designed, and experiments demonstrate the simulation system solves the dynamic real-time simulation of flight control software.
