Description

technical field [0001] The invention relates to the technical field of testing the flight control system of an unmanned aerial vehicle, in particular to a semi-physical simulation system and a simulation method for a light and small unmanned aerial vehicle. Background technique [0002] A semi-physical simulation system for small UAVs has been developed in China. In 2016, Xi'an Aircraft Design Institute of China Aviation Industry Corporation developed a UAV flight simulation demonstration platform based on serial port communication. The simulation computer uses the serial port to simulate navigation. The data is injected into the flight control system, and the flight controller uses the navigation simulation data to solve the control quantity and drive the actuator. The execution volume of the actuator is returned to the simulation computer through the serial port to form a closed loop to realize the test of the flight controller in the loop. The shortcomings of this method ...
