Open-closed loop combined semi-physical simulation method and system for medium and large unmanned aerial vehicles

Abstract

The invention discloses an open-closed loop combined semi-physical simulation method and system for medium and large unmanned aerial vehicles, and relates to the technical field of unmanned aerial vehicle flight control simulation. A simulation and test computer and a simulation management computer can independently carry out open-loop testing on the physical interface and interface program of a flight control and management computer. The simulation and test computer can flexibly simulate multiple communication interfaces by replacing an interface board card. An open-closed loop combined semi-physical simulation test is built at a lower cost. Key functions of an unmanned aerial vehicle system can be verified. Physical interface and codec program testing is carried out on a ground station,data transmission, the flight control and management computer, rudder control and a steering engine. Simulation testing is carried out on guidance and control parameters and flight management logic. The simulation management computer can be used to set the faults and meteorological conditions of a sensor, the steering engine and rudder control and test the robustness of flight control functions and the fault tolerance of flight management functions.

Description

technical field [0001] The invention relates to the technical field of UAV flight control simulation, in particular to a semi-physical simulation method and system for medium and large UAVs combining open and closed loops. Background technique [0002] In recent years, with the rapid development of UAV technology, UAVs of different configurations and weights are emerging, and are widely used in military, security, disaster relief, entertainment, agriculture, electric power and other industries. It can be mainly divided into two categories: one is light and small UAVs represented by multi-rotors and wing-rotor composites; man-machine. [0003] The flight control system is the core of UAV technology, and the semi-physical simulation system is the key to the development and testing of large and medium-sized flight control systems. [0004] For light and small UAVs, each system has simple functions, high maturity, short R&D cycle, and limited R&D funds. At the same time, due t...
