Design and analysis of fault observer of MIMO system with systematic error and measurement error. Issue 3 (21st September 2018) - Xingxing, Hua
ABSTRACT: A fault observer of the MIMO (multiple input multiple output) feedback fault system with measurement error and system error is designed and analysed based on the linear time-invariant system. First, the disturbance system with system error and measurement error in the case of failure is given. Second, the expression form of system error is obtained, and the system error is divided into the random error part and the error part generated by the system error at the last moment. Then, a fault diagnosis observer is given for a fault system with both system error and measurement error. Finally, simulation results are presented to show the effectiveness of the proposed method.
