摘要：
In order to improve the tracking performance of permanent magnet synchronous linear motor (PMSLM) and enhance the robustness of the system, a fractional order super-twisting sliding mode control strategy is proposed in this paper. Firstly, a generalized super-twisting observer is designed for the external disturbance and the unknown state of the system, which can accurately estimate the speed and external disturbance of PMSLM. Secondly, combined with the fractional order theory and terminal sliding mode control theory, a fractional order super-twisting sliding mode controller with finite time convergence is designed to realize the tracking control of PMSLM. Finally, the effectiveness of the proposed scheme is verified by simulation. © 2023 South China University of Technology. All rights reserved.
