Research ArticleOpen accessPhrase in the titleFixed-Star Tracking Attitude Control of Spacecraft Using Single-Gimbal Control Moment GyrosSangwon Kwon, Yuki Tani, Hiroshi Okubo, Takashi ShimomuraProblem statement: A cluster of small-sized Single-Gimbal Control Moment Gyros (SGCMGs) is proposed as an attitude control actuator for high-speed maneuver of small satellites. There exists a singularity problem what is peculiar to the CMG system. Approach: This study presented a simple singularity avoidance steering law using the Singular Value Decomposition (SVD) algorithm. Results: Capability of the present steering method … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,978 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleArchitecture for Combined Energy and Attitude Control SystemIbrahim Mustafa Mehedi, Renuganth Varatharajoo, Harlisya Harun, Mohd Nizam FilipskiCombining the energy and attitude control system is a feasible technology for small satellites to improve the space missions. In this Combined Energy and Attitude Control System (CEACS) a double rotating flywheel is used to replace the conventional battery for energy storage as well as to control the attitude of an earth oriented satellite. Each flywheel is to be controlled … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,404 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleVehicle-Fixed-Frame Adaptive Controller and Intrinsic Nonlinear PID Controller for Attitude Stabilization of a Complex-Shaped Underwater VehicleChanaka Thushitha Bandara, Lakmali Nadeesha Kumari, Sanjeeva Maithripala, Asanga RatnaweeraIn this study we present attitude stabilization using a vehicle-fixed-frame adaptive controller and an intrinsic nonlinear PID controller for a low-speed Autonomous Underwater Vehicle (AUV), of complex shape. Controlling an AUV poses a huge challenge because of the non-linearity, time variance and unpredictable external disturbance, as well as because its dynamics and hydrodynamic parameters are difficult to identify due to … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 7 Dec 2020 · 6,987 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAssessment of Knowledge, Attitude and Practices of Onchocerciasis Prevention and Control in Becho Woreda, Illu Ababora, Oromia Regional State, South West EthiopiaMasresha Leta Serbesa, Maleda Tefera, W/Michael Moroda BurayuOnchocerciasis is a filarial disease caused by onchocerca volvulus and transmitted by a black fly. Onchocerciasis is a killer of livestock and wild animals so Onchocerciasis prevention and control is helpful for health planners and health educators providing basic information to focus on its prevention and control. The objective of this study was to assess the knowledge, attitude and practice … …American Journal of Infectious Diseases, Vol. 15, Issue 2 · 4 May 2019 · 7,527 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleStabilized Controller Design for Attitude and Altitude Controlling of Quad-Rotor Under Disturbance and Noisy ConditionsM. Hassan Tanveer, S. Faiz Ahmed, D. Hazry et al.This article presents a control approach to obtain the better stabilization in attitude and altitude of quad-rotor under different disturbance conditions. In the standard Quad-rotor rotor type UAV, controlling of attitude and altitude is one of the most critical tasks and appropriate controller for stabilization of UAV is essential and necessary. These two controls under various conditions of disturbances was … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 8,524 accessesView PDF Cite
