Xingxing Chen, Ke Zhang, Bin Jiang · 2017
This paper concerns with the robust finite-time fault diagnosis of leader-follower multi-agent systems with actuator faults. Using linear matrix inequality (LMI) and robust finite-time boundedness theory, a sufficient condition is firstly presented for a dynamic system to be robust finite-time bounded. The observer is constructed based on relative output estimation error. Then the existence conditions of robust finite-time fault diagnosis observers are shown by means of LMI. According to the solution of LMI, the design method of the observer is given. Finally, two examples are given to illustrate the effectiveness of the proposed method.
