Abstract
In this article, a new supertwisting sliding mode direct thrust control (NSTSM-DTC) scheme is proposed to improve the dynamic response, robustness ability of the linear induction machine, and overall drive performance. First, a NSTSM algorithm is proposed and implemented in both electromagnetic thrust and primary flux-linkage control loops. The design aspects, implementation process, and stability analysis of the NSTSM based on the DTC method are fully investigated, which can effectively achieve faster dynamic response, smaller steady state speed tracking error, lower electromagnetic thrust ripple, and increase the system robustness against load variation in comparison to those of the conventional control methods. The proposed method is fully confirmed by the comprehensive simulations and experiments based on one prototype of 3 kW arc induction machine.Keywords
