Adaptive fixed-time hierarchical sliding mode control for switched under-actuated systems with dead-zone constraints via event-triggered strategy

作者：

Highlights：

• A HSMC for switched under-actuated systems with input dead-zone is proposed.

• The event-triggered mechanism is applied to save communication resources.

• A projection algorithm is introduced to avoid the singularity problem.

• A fixed-time control is proposed to ensure that all singals are fixed-time bounded.
