title = "Sensor fault detection for linear systems by multiple H-lH∞observers",
abstract = "In this paper, the problem of sensor fault detection (FD) for linear discrete-time systems has been studied with the aid of multiple H-l H∞ observers approach. A limited number of fault modes can be obtained by considering the system only occurs one fault at a time. For each fault mode, an Hl H∞ fault detection observer (FDO) is designed with its residual is sensitive to fault and robust to disturbances and noises. Meanwhile, each FDO is optimized for the certain fault mode to improve the performance of fault detection. By assuming the disturbances and noises are unknown but bounded, zonotopic techniques are used to achieve residual evaluation based on the designed H-l H∞ FDQs. Finally, a second-order RC circuit simulation example is utilized to illustrate the effectiveness of the proposed method.",
