This paper deals with the design of neural network controller for the slung-load system. There are many methods for modeling the slung-load system, we developed the entire system model based on the UKE (Udwadia-Kalaba Equations) in order to account for multiconstraints. Neural network was adapted to the attitude controller. Finally, considering all matters in the design process, numerical simul...

TraQuad is an autonomous tracking quadcopter capable of tracking any moving (or static) object like cars, humans, other drones or any other object on-the-go. This article describes the applications and advantages of TraQuad and the reduction in cost (to about 250$) that has been achieved so far using the hardware and software capabilities and our custom algorithms wherever needed. This descript...

Abstract: This paper presents a nonlinear H∞ control law for underactuated mechanical systems with input coupling. Apart from the controlled degrees of freedom (DOF), the proposed controller considers the dynamics of the remaining DOF in the cost variable, which allows to stabilize them. The underactuated mechanical system is normalized to obtain a diagonal inertia matrix allowing to weigh with...

Inertial navigation systems are used in many situations where the use of an external reference to measure position is impractical or unreliable. Typical inertial navigation systems used in aeronautics and marine applications are highly advanced pieces of equipment costing thousands of dollars. However, inexpensive accelerometers and angular rate sensors (gyros) can be used to make a far less ac...

The main motivation of this work is to propose a simulation approach for specific task within the Unmanned Aerial Vehicle (UAV) field, i.e., visual detection and tracking arbitrary moving objects. In particular, it described MAT-Fly, numerical platform multi-rotor aircraft characterized by ease use control development. based on Matlab MathWorks Virtual Reality (VR) Computer Vision System (CVS) ...

Recently, application field of drone is expending throughout the growth technology in structural change whole society which calls 4th industrial Revolution. So, construction has been already using video shooting design and efforts to introduce drone, one smart technology, are also increasing even facility maintenance management. It takes so much time costs train experts who required training co...

The quad/triangular subdivision, whose control net and refined meshes consist of both quads and triangles, provides better visual quality of subdivision surfaces. While some theoretical results such as polynomial reproduction and smoothness analysis of quad/triangle schemes have been obtained in the literature, some issues such as the basis functions at quad/triangle vertices and design of inte...
