چکیده

کنترل مناسب دینامیک طولی خودرو نیاز به داشتن اطلاع دقیق از مقدار پارامترهای دینامیک خودرو دارد. در این مقاله الگوریتم تخمین پارامتر با نام فرم درجه دوم خطی به صورت زمان کوتاه (STLQF) برای تخمین هم‌زمان پارامترهای جرم خودرو، زاویه شیب جاده و ضریب درگ کلی آیرودینامیک خودرو توسعه داده می‌شود. سپس، کارکرد موثر تخمین‌گر STLQF با مقایسه عملکرد این تخمین‌گر با روش حداقل مربعات بازگشتی (RLS) نشان داده می‌شود. در پایان، الگوریتم STLQF به صورت سخت‌افزار در حلقه شبیه‌سازی می‌شود تا از این طریق تخمین‌گر STLQF با حداقل هزینه و در کوتاه‌ترین زمان برای نمونه‌سازی سریع توسعه پیدا کند.
