Under this model and under some conditions, a fault estimation method is proposed to estimate the system faults.
A finite frequency fault estimation observer is proposed to estimate the actuator fault in the entire frequency domain.
A fault estimation approach is presented to estimate the fault and the estimation error is dependent on the bounds on the uncertainty.
Based on the descriptor system model, a fault estimation filter which can simultaneously estimate the state and the sensor fault magnitudes is designed via a minimum-variance principle.
The proposed fault estimation method provides a direct estimate of the size and severity of the fault, which can be important in many civil engineering applications.
Furthermore, an observer-based fault estimation method is provided to estimate the size of the fault.
Due to the dependency of the FTTC strategy on the fault estimation the designed observer has the capability to estimate a wide range of time varying fault signals.
Due to the dependency of the FTC strategy on the fault estimation the designed observer has the capability to estimate a wide range of time varying fault signal.
A further feedback loop exploits the fault estimation to accommodate faults affecting the system.
