N2 - To improve the dynamic response of the linear induction machine (LIM) over its complete speed range, this paper introduces a finite state-model predictive voltage control (FS-MPVC) based on terminal sliding mode control (TSMC). First, the TSMC for the speed loop is designed to attain high tracking capability and faster transient response. Second, in terms of the intricate balancing coefficient tuning difficulty and several computation steps of the conventional finite state-model predictive thrust control method, the control objectives are transformed to the primary voltage based on the FS-MPVC method. Furthermore, the TSMC-MPVC is fully studied in detail, covering its design and implementation steps. Ultimately, a 3 kW LIM has undergone comprehensive simulation evaluations by the presented TSMC-MPVC through comparing with the conventional methods at various speeds and loads to verify the effectiveness and viability of the proposed method.
