A Software-Defined an emerging networking paradigm simplifies architecture by decentralizing plane functionality into a single with centralized decision capabilities. Along...

In this paper, a novel control strategy based on model predictive is proposed for tracking the trajectory of unmanned aerial vehicles (UAV). First, dynamic an vehicle UAV established by considering linear velocities in terms analyzed system's attitude angles. The UAV's suitable kinematic using two angles as inputs. controller design made up output feedback formed error variables, which are difference between measured and reference variables. Then, optimization problem with performance index...

Multi-Inputs-Multi-Outputs (MIMO) systems are recognized mainly in industrial applications with both input and state couplings, uncertainties. The essential principle to deal such difficulties is eliminate the then estimate remaining issues real-time, followed by an elimination process from channels. These resolved this research paper, where a decentralized control scheme suggested using Improved Active Disturbance Rejection Control (IADRC) configuration. A theoretical analysis state-space...

Wind power has become one of the leading clean and inexhaustible sources today's electricity generation. turbines are significantly evolving with tremendous benefits, resulting in remarkable demand installing establishing new wind farms.
