Kiểm soát ổn định tư thế vững chắc trong thời gian hữu hạn cho spacecraft cứng dưới ràng buộc vận tốc góc dựa trên mạng nơ-ron
Tóm tắt
Trong bài báo này, vấn đề kiểm soát ổn định tư thế của spacecraft trong điều kiện ràng buộc vận tốc góc được nghiên cứu. Một kế hoạch kiểm soát tư thế trong thời gian hữu hạn tuân theo ràng buộc trạng thái được thiết kế bằng cách tận dụng triệt để đặc điểm mô hình của quaternion. Dựa trên phương pháp chi phối đồng nhất, tính ổn định trong thời gian hữu hạn của hệ thống vòng kín được chứng minh. Nghiên cứu chứng minh rằng vận tốc góc có thể được giữ trong khoảng giới hạn vào bất kỳ thời điểm nào. Đối với hệ thống con động lực học vòng tư thế có nhiễu bên ngoài, một bộ điều khiển trượt tận cùng tích phân dựa trên mạng nơ-ron cơ sở bán kính được đề xuất. Cuối cùng, tính hợp lệ và những ưu điểm của kế hoạch điều khiển được đề xuất được chứng minh qua phần mô phỏng so với hai phương pháp điều khiển khác.
