20.500.12556/DKUM-91798 Sensitivity analysis of MTPA control to angle errors for synchronous reluctance machines This study investigated the sensitivity of maximum torque per ampere (MTPA) control in synchronous reluctance machines (SynRMs) to angle errors, examining specifically how deviations in the reference control trajectory affected performance. Analytical and numerical methods were employed to analyze this sensitivity systematically, including the impact of magnetic saturation. Two MTPA control implementation schemes were evaluated, with torque and current amplitude as the reference variables, using a template SynRM from the open-source simulation tool SyR-e. The results indicated that performance sensitivity to angle errors was moderately low near the MTPA trajectory, allowing for significant angle deviations with minimal performance loss. Although magnetic saturation increased this sensitivity slightly, reducing the allowable error range by up to 25%, the maximum angle deviation for up to 1% of the performance decrease still corresponded to approximately ±3∘ around the MTPA trajectory. The findings of this study suggest potential for simplifying control implementations, reducing component costs through less precise position determination (sensor-based or sensorless), and achieving additional control objectives such as torque ripple reduction. control angle error finite element method MTPA control sensitivity to performance decrease suboptimal operation synchronous reluctance machines sinhroni motorji metoda končnih elementov true true false MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/2227-7390/13/1/38 © 2024 by the authors Članek v reviji 2025-02-07 10:58:59 2025-02-07 10:59:00 2025-02-08 03:12:16 0000-00-00 00:00:00 2025 0 0 23 str. iss. 1, [article no.] 38 Vol. 13 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-12-23 2024-12-24 2024-12-26 621.31 222381059 10.3390/math13010038 2227-7390 mathematics-13-00038-v2.pdf mathematics-13-00038-v2.pdf 1 07ECB6C21D8EDFF13F819FF04C591849 ec5c49194aed5ee54643f8947d362b794be26ea41b9ceb15b5a1b33db3da21ff 5a1af3cd-e53a-11ef-a41d-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188499 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
