This article proposes a new control strategy to regulate the six-phase induction machine fed by a nine-switch converter. The traditional model predictive control method is a favorable feedback control routine in variable-drive applications. However, the lack of the term that assess the closed-loop stability in the conventional cost function formulation may cause potential closed-loop instability and be incapable of tolerating the parameter mismatch. Furthermore, the conventional model predictive control formulation cannot ensure global optimality in case of deviation from the nominal operating point. In this paper, the closed-loop stability is enhanced by including a sliding mode stability term in the objective function. The traditional cost function is redeveloped as a sliding mode control stability term, and the selection of the control input that satisfies the closed-loop loop stability condition is ensured. The robustness performance of the system is improved, and a better steady-state performance is achieved. The proposed control strategy is proved using a hardware setup including a six-phase 30 spatially shifted induction motor and nine-switch converter prototype. The experimental results demonstrate that a secured sixphase induction motor operation is guaranteed while improving the closedloop robustness.

“…Sliding mode control (SMC) is recognized as one of the well-established control strategies suitable for power converters. [12][13][14][15] Sliding mode usually appears in a dynamic system governed by ordinary differential equations. Conceptually, the control input signal is expressed as a function of the control goals, and it switches at a certain frequency.…”

This work introduces a novel dual-sliding mode control approach for nineswitch inverter topology. The nine-switch inverter helps regulate multiple acloads by using fewer semiconductor devices than the conventional two parallel voltage source inverter system. However, achieving independent control of two sets of ac loads is not a straightforward task when a nine-switch inverter feeds separate load stages. Regarding this consideration, a dual-sliding mode controller that includes a specific decision-making algorithm can be an efficient solution for a multi-load control problem. The proposed strategy offers a good compensation performance for the unconnected load stage under different load utilization profiles. The designed closed-loop system has a rapid response to sudden load change, and no unwanted interaction between individual load stages is observed. The detailed design steps and performance analyses are reported. Experimental results demonstrate the capability and usefulness of the proposed control strategy.
