Automatic Take-Off of Finite Damaged UAV
The research and development on UAVs have been booming all over the world recently because of UAVs’widely use in military and civil field,especially its’unique role in modern war.Running take-off is a complex phase in the whole flight process.Similarly,UAV’s take-off is also a crucial technique in the research of UAVs.Especially in some unusual conditions,the running take-off [...]
Research of Rutch Roll Modal of Unmanned Aerial Vehicle with the Limited Deadlocking of Single Aileron
Under a hazardous environment UAV often goes wrong, so it is important to study UAV’s motion characteristics and controlled it effectively, then make it out of unstable flight state. This paper studies how to reasonably tune the control distribution of the system under fault of the single aileron deadlocking while UAV is subjected side direction [...]
The Study of UAV Flight Path Tracking Control Method
UAV (Unmanned Aircraft Vehicle) has become more and more widely used in the civil and military fields,the development of UAV has also attracted the attention of countries in the world. The flight path tracking control plays an particular important role in UAV flight, which can further improve the dynamic performance of UAV and provide powerful [...]
Research on Separation Phase of Uav in Different Separation Configurations
Ground launching of UAV is a potential technology which will greatly improve effectiveness and application rang of UAV. Rocket booster ground launching is a technology which has a high degree of difficulty and multiple influence factors.Based on the research on different installation configurations of booster rockets, a preliminary analysis of their dissimilar characteristics from the [...]
The Research of Path Planning Based on Velocity Vector Field
With the development of UAV (Unmanned Aerial Vehicle) technology, the path planning, especially real-time planning, is playing a more important role in UAV’s fight control system. A real-time planning technology base on velocity vector field which used in local planner is presented in this paper. The main contributions are summarized as follows:According to requirements of [...]
The Design of Inertial Measurement Unit Based on MEMS
An IMU (Inertial Measurement Unit) for mini-UAV (Unmanned Aerial Vehicle) based on MEMS (Micro-electromechanical Systems) was designed by this paper, aiming to measure the attitudes of UAV real time, such as triaxial accelerations, triaxial angular rates, roll angle and pitch angle. Firstly, the IMU scheme was developed based on MEMS with the view of applying [...]
Research on Lateral Flight Control System of the Unmanned Aerial Vehicle
The Unmanned Aerial Vehicle (UAV) is a kind of vehicle which is controlled by radio remote control equipment or the control program of its own. The UAV has many advantages, such as wide usage, low cost, cost-effective, no casualty risk, ease of use and so on. As a result, the UAV plays a very important [...]
