摘要
This brief study finite time fault estimation problem for switched systems with lager and fast time varying fault. Coordinate transformation is implemented, and then the reduced order observer is designed to estimate the system state and fault. Neither the fault nor the fault derivative exists in the estimation error system, then the proposed fault estimation method will not be affected by the large value fault and fast time-varying fault. Furthermore, Based on the finite time output boundedness definition and average dwell time, the LMI conditions are achieved to insure that the error system is finite time output boundedness. Finally, the switching circuit is considered to verify the technique.
