Research and implementation of multi-function missile borne control system based on DSP

Based on the principle of one-dimensional trajectory correction projectile, a multi-function Missile Borne control system is designed to achieve a secondary correction, In order to achieve the function of one-dimensional trajectory secondary correction, in other words, to achieve the "distance & precision" correction function, floating-point DSP processor TMS320F28335 is utilized as the core controller aided with peripheral circuit. The multi-function Missile Borne control system includes power management, communication module, GPS signal processing, trajectory tracking control, command signal generation, boosting & detonating module and data storage module. On the basis of the above, the supporting hardware and software is completed. By the hardware-in-the-loop simulation and experimental studies, its function is verified, The result of the semi-physical simulation and experiments show that multi-function missile borne control system utilizing DSP as its core controller could achieve the function of one-dimensional trajectory secondary correction. Its control capability and real-time performance fully meet the requirements of trajectory correction.
