Description

technical field [0001] The invention relates to a rapid prototype design and semi-physical simulation method and system of a flight control system, belonging to the field of flight control. Background technique [0002] The design of the flight control system can be divided into two main stages: theoretical design stage and engineering design stage. [0003] Theoretical design stage: Mainly according to the system function and performance requirements, use appropriate design theory to design the control law, that is, the control command algorithm of the controller or computer. After the design is completed, the control law is verified through mathematical simulation, that is, the function and performance test. [0004] Engineering design stage: It is necessary to design the hardware configuration of the system and write the software at the same time. And through the manufacture of the principle prototype to verify whether the results of the theory and engineering design mee...
