Altitude Control for Small Fixed-Wing Aircraft Using H-infinity Loop-Shaping Method
(Elsevier Science BV, 2016)
Autopilot systems for UAVs without human pilots maintain the flight through an appropriate balance of aerodynamic forces autonomously. That is to say, they arc used to make flight missions more reliable and efficient. ...
Design of a Sliding Mode Controller for Quadcopter
Nowadays, unmanned aerial vehicles became an important research area. Search and rescue, transportation, fire monitoring, commercial and journalism, military and defence, crop spraying and scientific research are some of ...
Nonlinear modelling and control of the flow over aerofoils using CFD simulations
(Elsevier B.V., 2016-09)
A simulation based approach for nonlinear dynamical modelling and feedback control of the drag to lift ratio for aerofoils is investigated through case studies involving NACA 23012, ag13 and b737a aerofoils. The flow around ...
Performance improvement of a photovoltaic system using a controller redesign based on numerical modeling
(Pergamon-Elsevier Science Ltd, 2016-08-03)
This paper focuses on the utilization of numerical modeling and simulation to improve the performance of a theoretically designed stand-alone photovoltaic (PV) system with constant DC voltage. A theoretically designed ...
Design of a flight stabilizer system and automatic control using HIL test platform
(International Journal Of Mechanical Engineering And Robotics Research, 2016)
In this paper a Hardware-In-the-Loop (HIL) test platform is used to design a flight stabilization system for Unmanned Aerial Vehicles (UAV). Controllers are first designed and tested separately for lateral and longitudinal ...
