We examine the path-following guidance of a UAV in three-dimensions and in the presence of quasi-constant but unknown wind disturbances. The analysis and control design are based only on a kinematic model. A first contribution is an alternative description of the dynamics that simplifies the design. A second contribution is the derivation of a guidance law that ensures the global asymptotic convergence...
The accuracy of the most commonly used integrated navigation system of inertial navigation system (INS) and global navigation satellite system (GNSS) is greatly influenced by the quality of satellite signals. Based on the most commonly used navigation system that is equipped with barometer and airspeedometer, a new navigation algorithm is proposed for fixed-wing unmanned aerial vehicles (UAVs) to...
In order to implement the maximal power tracking control of brushless doubly-fed wind power generation system, direct torque control (DTC) is adopted based on the power output characteristics of wind turbine. And for the problem of the bad robustness of flux observation as brushless doubly-fed generator (BDFG) running at lower excitation current frequency of control winding side, a sliding mode flux...
