Switched sliding mode control

This paper proposes a switched sliding mode control (SSMC) method grounded on the switching control and the sliding mode control, which enhances the control performance by switching among appropriate sliding mode controllers according to different regions of the state space. The SSM simultaneously has the characteristic of global high-speed convergence compared with the nonsingular fast terminal sliding mode (NFTSM), the property of global finite-time convergence, which the NFTSM does not have, and also avoids the singularity globally. The simulation study is conducted to demonstrate the effectiveness of the proposed approach.
