Use of unmanned aerial vehicles is considered as one of the means which performs infrastructure inspection. Since the operation from GPS or the outside is not needed but the method by a quadrotor with a tether can perform the position control of the airframe, it can be used for the inspection of infrastructures, such as a tunnel and a bridge. In this research, it aims to develop and control a camera...
An X4-AUV is nonlinear, coupled and unstable system. In this paper, we present the results of two control schemes applied to an X4-AUV. A direct use of Lyapunov control theory and PD controller technique and backstepping technique have been applied to stabilize the system. We performed the simulations to see the comparative performance result of an X4-AUV under two control schemes.
An unmanned small aircraft is expected to be applied to various applications, such as aerial photography, information gathering of disaster, transport of luggage, and inspection of infrastructure, such as bridges and tunnels. It needs to control the position of the Quadrotor, if it is used for the inspection of infrastructures, such as bridges etc. Therefore, we propose a method for controlling a...
