N2 - This paper proposes a novel self-healing control method for satellite attitude tracking based on simultaneous fault estimation and control design. The proposed method integrates the fault estimation and fault-tolerant control units in a dynamic system, which is less complex and more reliable than the separately designed self-healing architectures. In this paper, the model reference approach is used to obtain a tracking error dynamic equation. Following this, an augmented error system is constructed by taking the fault as an auxiliary vector. Based on the augmented error system, a fault estimator/controller is designed to achieve robust fault-tolerant control and robust fault estimation simultaneously. The design conditions for the proposed fault estimator/controller are transformed as a set of linear matrix inequalities, which can be easily solved. Finally, numerical simulation results are given to demonstrate the effectiveness of proposed method.
