Attitude Control for Magnetic Actuated Satellite
Absract Magnetic actuation utilizes the mechanic torque that is the result of interaction of the current in a coil with an external magnetic field. A main obstacle is, however, that torques can only be produced perpendicular to the magnetic field. This actuation principle has been a topic of research since earliest satellites were launched. Magnetic control has been applied for nutation damping...
متن کاملSliding Mode Control for Attitude Tracking of Thruster-Controlled Spacecraft
Nonlinear pulse width modulation (PWM) controlled system is considered to achieve control performance of thrustercontrolled spacecraft. The actual PWM controlled motions occur, very closely, around the average model trajectory. Furthermore nonlinear PWM controller design can be directly applied to thruster controlled spacecraft to determine thruster on-time. Sliding mode control for attitude tr...
متن کاملDesign of Sliding Mode Attitude Control for Communication Spacecraft
Control problem of a spacecraft is an important topic in automatic control engineering. A body orbiting the Earth in geosynchronous orbit has instabilities in attitude dynamics and disturbances caused by the Earth, the Moon, the Sun and other bodies in space. These effects force the body to lose initial orbit and attitude. Here the control system takes important part of spacecraft missions wher...
متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
متن کاملSliding Mode Control of an MRI-Compatible Pneumatically Actuated Robot
Magnetically sensitive environments such as MRI scanners preclude the use of traditional electromagnetic actuators. Pneumatic piston-cylinders are well-suited actuators for MRIguided robots, but the nonlinear dynamics of the working fluid creates a challenging controls problem. Precision control of the actuators is needed for the robot to achieve high targeting accuracy. This paper reports a fi...
