Real‐Time Sliding Mode Control Using Space Vector Modulation for Six‐to‐Three‐Phase Indirect Matrix Converters

Year: 2025

Type: article

Abstract: ABSTRACT The central focus of this study is the integration of a high‐performance six‐phase permanent magnet synchronous generator (HPSG) with a three‐phase grid, aiming to eliminate passive components such as capacitors and enhance power injection. The proposed solution uses an indirect matrix converter (IMC) based on space vector modulation (SVM) and compares three control strategies: the classical sliding mode controller with hyperbolic functions (SMC), the second‐order PI controller (2nd‐PI), and the integrator‐based linear quadratic regulator (IB‐LQR). The evaluation is performed under dynamic conditions using real‐time simulation. A high voltage transfer ratio (VTR) of up to 96.6% is achieved. System performance and stability are validated through closed‐loop simulations on a 1.35 MW inductive load. Results show that the SMC controller offers superior convergence and tracking (IAE, ISE, ITAE, ITSE) under three‐phase short‐circuit and dip voltage tests, compared to IB‐LQR and 2nd‐PI. However, SMC suffers from chattering and overshoot in the ‐axis. IB‐LQR demonstrates consistent robustness under disturbance, while 2nd‐PI offers a simpler and effective solution in steady‐state operation. Furthermore, total harmonic distortion (THD) analysis at the point of common coupling (PCC) confirms that SMC provides the best harmonic mitigation among the three controllers.
