Dynamic event-triggered fault estimation and sliding mode fault-tolerant control for networked control systems with sensor faults

作者：

Highlights：

• The system state is reconstructed, and a dynamic event-triggered scheme is designed to conserve the limited communication resources.

• Considering the influence of network delay, dynamic event-triggered scheme and system fault, fault/state observer is designed and sliding mode surface is constructed.

• A sliding mode controller under dynamic event-triggered scheme is designed to ensure that the trajectories of the system can reach the sliding surface.
