Abstract. Air-core magnetotorquer-only attitude control system (ACS) for the low-cost, spin-stabilized ITASAT satellite is here described. ITASAT’s ACS has been tested by simulation with synthetic measurement data. The proposed closedloop ACS system is based on 3-axis attitude and angular rate estimates provided by an extended Kalman filter processing vector measurements from a Sun sensor and a...

There is a substantial amount of literature within the field of spacecraft control which deals with the separate issues of position and attitude control; comparatively little work has been carried out on the joint nonlinear problem of spacecraft position and attitude control. (R.Pongvthithum etal 2005, H.Wong etal 2001, S.M.Veres etal 2002) provide control solutions for spacecraft position cont...

This paper proposes a new concept for attitude actuation for small satellites that uses active magnetic bearings to support and tilt a spinning rotor to provide 3-axis attitude control of the satellite using a single actuator. A controlled 3D motion in the spinning rotor provides a conventional torque output about the momentum axis and a gyroscopic torque output about any direction in the plane...

The satellite thruster's configuration plays also an important role in providing the attitude control torques. In this paper, after discussing the gimbal thruster's structure and its benefits, several configurations based on 2, 3 and 4 gimbal thrusters are investigated in order to identify the most suitable orientation that consume less fuel and raise reliability. Then, a 3-axis attit...

Abstract: This paper presents the development and implementation of a single tilting rotor multirotor helicopter. A single tilting rotor multirotor helicopter is proposed that allows for decoupled lateral acceleration and attitude states. A dynamics model of the proposed multirotor helicopter is established to enable control system development. A control system architecture and daisy chaining-b...

It is well-known that the multiple sliding surface control was developed to eliminate the problem of ‘‘explosion of complexity’’ inherent in the celebrated backstepping method. In this paper, we extend the multiple sliding surface control method further for systems in nonlinear block controllable form. As an application of the proposed control scheme, the robust attitude control law was synthes...
