摘要：

In this paper, the problem of sensor fault estimation and compensation for microsatellite attitude dynamics is investigated by using a descriptor system approach. Firstly, a linear model of microsatellite attitude dynamics is given. Based on the proposed linear microsatellite attitude dynamics, an augmented descriptor system is constructed by letting the sensor fault term be an auxiliary state vector. Using linear matrix inequality approach, a state-space observer is designed for the augmented descriptor microsatellite attitude dynamics, which can estimate microsatellite attitude dynamics state vector and sensor fault simultaneously. In terms of the estimated sensor fault information, sensor fault compensation is also performed. Finally, a simulation example is given to illustrate the effectiveness and potential of the proposed techniques.
