Design and Validate by Semi-physical Simulation for Unmanned Helicopter Control of Automatic Guidance and Landing
Usually,the automatic landing guidance control method of unmanned helicopter is:an i-deal flight path is generated for the task requirements in real time by the guidance system according to the detected position information of aircraft and ship.According to the certain guidance law,the guidance instructions are calculated and sent to the flight control system.After calculation and trans-formation,the final position,speed and attitude control instructions are obtained,and the unmanned helicopter is controlled to track the ideal trajectory,and then the unmanned helicopter can return to the ship and land.In this paper,according to the characteristics and requirements of unmanned hel-icopter automatic guidance and landing,the obtained relative position information was directly sent to the unmanned helicopter flight control system,and the automatic landing progress and correspond-ing control law were designed.Given the speed and position control instructions,the flight attitude of the unmanned helicopter was adjusted in real time,and the multi-mode composite control was a-dopted.Finally it guided the unmanned helicopter to complete the whole process of returning to the ship,approaching the ship and landing,and it was verified by semi-physical simulation test.
