Design And Development Of UAV Control System

With the promotion of carrying out "one belt and one road" policy,More and more attention has been paid to the effective exploitation and utilization of resources,UAV,as an efficient and low-cost tool,will be more appropriate to perform a number of high-altitude and dangerous tasks.According to the characteristics of single UAV,a method of multi UAV cooperative control is proposed,according to the advantages and disadvantages of the existing achievements at home and abroad to demonstrate the feasibility and effectiveness of the development,in this framework,the development of multi UAV network is developed,to enable it to meet the requirements of the cooperative control task.In this paper,the main technology of single UAV is introduced in detail.We exploring the structure of UAV,and the motion control model of UAV is established,the motion state of the current model is analyzed and constructed,the motion equation is established based on the position motion of a single UAV in 6 spatial directions,and according to the corresponding influence factors to calculate the subsequent trajectory,at the same time,the mechanical analysis of the 4 propellers of the UAV is carried out,and the necessary factors of the UAV in the normal mode are analyzed,makes the UAV's stable cruise become a reality.Based on the above results,the state of UAV is modeled,and the abstract data is transformed into the data which can be calculated,it provides a guarantee for UAV's precision control and obstacle avoidance.According to the principle and requirement of UAV,the motion control unit is designed,the data of the position and the stability of the UAV are calculated by using the data of the sensors,the stability of the body is calculated,the attitude controller of UAV provides the guarantee for the stability of the underlying system,the position controller provides the guarantee for UAV autonomous flight and multi task coordination,on this basis,the cooperative mechanism of UAV is designed and described,which makes the cooperative work of UAV become a reality.After the above calculation and planning,continue to make the UAV hardware and program platform,the task control system and the attitude control system are designed,the function of the upper system is to command the UAV to perform the specified task,the function of the lower level attitude system is to perform the assigned task according to the command of the upper layer.After testing,the system can meet the requirements of UAV cooperation.
