ملخص المقالة :
در اين مقاله، يک کنترلکننده جديد براي پايدارسازي جانبي خودروهاي الکتريکي چهارچرخ محرک بدون ديفرانسيل پيشنهاد شده که روش کنترلي پيشنهادي شامل سه سطح بالا، متوسط و پايين ميباشد. در سطح بالای کنترلکننده، ديناميکهاي مطلوب خودرو يعني سرعت طولي و نرخ ياو مرجع تعيين ميشوند. در این مقاله، يک ساختار جديد براي روش کنترل مد لغزشي پيشنهاد شده و پايداري آن توسط تئوری پایداری لیاپانوف اثبات گرديده است. این روش کنترل مد لغزشی نسبت به کنترلکننده مد لغزشي معمولي مقاومتر، سريعتر و داراي نوسانات کمتري حول پاسخ است. کنترلکننده سطح متوسط جهت رسيدن به نيروي رانش و ممان ياو مطلوب، بر اساس روش کنترل مد لغزشی پیشنهادی، طراحي گرديده است. در سطح پايين با تعريف و مينيممکردن بهينه يک تابع هزينه، سيگنالهاي نيرو و گشتاور مناسب براي اعمال به چرخها تعيين گردیده و در نهايت کارایي کنترلکننده پيشنهادي با انجام شبيهسازي در نرمافزارهاي MATLAB و CARSIM تأييد شده است.
