LS2K1000-based single-board flight control computer design and its semi-physical simulation

In view of the increasing requirements of civil aircraft for higher performance and lower power consumption of the main control processor of the flight control computer, a single-board flight control computer design is proposed which uses a high-performance embedded processor as the main control processor. This design uses the LS2K1000 embedded processor from Loongson and mainly includes the design of system architecture, minimum system circuit and functional circuit. The functional verification of the single-board flight control computer is completed on a self-built semi-physical simulation platform based on FlightGear/Simulink. The verification results show that the design can realize basic functions of data collection, signal conversion, control instruction calculation and other functions of the flight control system, and has certain practical engineering value.
