Adaptive Fixed-Time Control for Full State-Constrained Nonlinear Systems: Switched-Self-Triggered Case
Ziming Wang, Xin Wang, Ning Pang
Abstract
In this brief, an one-to-one asymmetric NM based auxiliary system is put forward to deal with the state transformation problem for nonstrict full state-constrained systems under the adaptive fixed-time control. Then one proposed a novel switched-self-triggered mechanism (SSTM) in the controller update, which is helpful to obtain a better system performance. In addition, one can show that under the condition of state-constraints, semiglobal practical fixed-time stability (SPFTS) standard can also preserved both the tracking performance and the stability of the closed-loop system in a specified time. Finally, the effectiveness of the controller design is thoroughly shown via an illustrative simulation example.
