Attitude Control of Underactuated and Momentum-Biased Satellite Using State-Dependent Riccati Equation Method

Attitude Control of Underactuated and Momentum-Biased Satellite Using State-Dependent Riccati... This paper deals with the attitude control problem of an underactuated satellite controlled by two reaction wheels. The angular momentum of the satellite is assumed to be non-zero or biased. Under these conditions, rotation to arbitrary attitude (roll, pitch, and yaw) is not possible, but direction or limited attitude control (roll and pitch) is possible. For such control, a nonlinear controller is proposed to utilize the angular momentum as gyroscopic torque. The controller is designed using the State-Dependent Riccati Equation (SDRE) method. This SDRE method provides a systematic way to design nonlinear controllers for diverse combinations of two reaction wheels. The proposed method has been verified by numerical simulations and the designed control system works satisfactorily. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Aeronautical & Space Sciences Springer Journals

Abstract

This paper deals with the attitude control problem of an underactuated satellite controlled by two reaction wheels. The angular momentum of the satellite is assumed to be non-zero or biased. Under these conditions, rotation to arbitrary attitude (roll, pitch, and yaw) is not possible, but direction or limited attitude control (roll and pitch) is possible. For such control, a nonlinear controller is proposed to utilize the angular momentum as gyroscopic torque. The controller is designed using the State-Dependent Riccati Equation (SDRE) method. This SDRE method provides a systematic way to design nonlinear controllers for diverse combinations of two reaction wheels. The proposed method has been verified by numerical simulations and the designed control system works satisfactorily.
