Ground test device used for flight control system and control method

Abstract

The invention discloses a ground test device used for a flight control system and a control method. The device comprises a carrying platform system, a motion control system, a flight control system, a remote controller, a receiver, a power supply system, a communication system and an upper computer, and the control method and a test method are included. Three working modes of the test device are achieved, one mode is that the test device moves under the control of the flight control system, one mode is that the test device moves under the control of the remote controller, and another mode is that the test device performs line-cruising motion. The three working modes can be conveniently switched. When the test device moves automatically under the control of the flight control system, a speed control loop and a direction control loop of the motion control system are used for making the test device visually simulate the motion, in an automatic drive mode, of an unmanned aerial vehicle and verifying algorithmic reasonability in the flight control system. Due to the fact that the three working modes are provided, the performance of the flight control system can be tested on the ground to a greater degree, system parameters can be effectively tested at the testing stage of flight control system designing, and reasonability and effectiveness of the control loops, a navigation algorithm and others can be verified.

Description

technical field [0001] The invention relates to a ground test device and a control method for a flight control system, which are applied to the ground performance test of the flight control system of an unmanned aerial vehicle and an unmanned airship, and belong to the technical field of ground simulation testing of the flight control system. Background technique [0002] Traditional ground tests for flight control systems are mostly cart or sports car experiments. Usually, the flight control system is installed on a small four-wheeled cart or car, and the car body is manually driven or driven. Attitude and position data are then collected for analysis and comparison. With this method, there are disadvantages that the ground test device cannot operate automatically, and is large in size, requires a lot of manpower, and the functions and items that can be tested are limited. Therefore, there is an urgent need for a device that has a small investment and can simulate and test...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to solve the problem that the traditional sports car or cart experiment used in the flight control system is large in size, and the tested data and functions are limited. The comparison method of online data and flight control data can simulate and test the performance of the flight control system to a greater extent.
