چکیده

This paper presents an Enhanced Model-Free Sliding Mode Control (EMFSMC) method tailored for the speed loop of a ۱۲-slot/۱۹-pole yokeless and segmented armature axial flux-switching permanent magnet (۱۲S/۱۹P YASA-AFFSSPM) motor, focusing on robustness against parameter perturbations. Traditional control techniques, such as Proportional-Integral (PI) control and Model-Free Sliding Mode Control (MFSMC), have shown limitations in handling the motor's nonlinear behavior and susceptibility to disturbances. The proposed EMFSMC algorithm optimizes speed loop performance by establishing a hyperlocal model of the YASA-AFFSSPM motor, which accounts for parameter variations. An improved double-power combinatorial reaching law is developed to enhance convergence rates during the sliding surface approach phase, while an Extended Sliding Mode Disturbance Observer (ESMDO) provides real-time monitoring of unknown disturbances affecting speed control. Simulation results demonstrate that the EMFSMC significantly accelerates the speed response time to approximately ۰.۰۱۵ seconds with minimal overshoot, compared to ۰.۰۴ seconds and a ۱۲.۵% overshoot with the MFSMC. Additionally, under sudden load conditions, the EMFSMC controller exhibits a speed drop of only ۴ rpm, recovering to stability in about ۰.۰۱ seconds, while the MFSMC controller experiences a ۹ rpm drop with a recovery time of ۰.۰۳ seconds. These findings confirm that the EMFSMC enhances the speed response rate and robustness of the speed loop, outperforming traditional control methodologies across various operating conditions.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
