Event-based joint state and fault estimation: The envelope-constrained H∞ criterion

作者：

Highlights：

• The joint state and fault (including both the sensor fault and the actuator fault) estimation issue is, for the first time, considered for a class of time-varying systems under the DETS.

• The DETS is applied to orchestrate the transmission of the measurement output from the sensor to the estimator for the purpose of reducing the unnecessary waste of resources.

• A unified theoretical framework is established to ensure that estimation errors of both the state and the fault satisfy the envelope constraint and the H∞ disturbance rejection level.
