NGHIÊN CỨU KHẢ NĂNG THAY THẾ BỘ ĐIỀU KHIỂN PI VÀ BỘ ĐIỀU KHIỂN MỜ BẰNG BỘ ĐIỀU KHIỂN DỰA TRÊN ĐẠI SỐ GIA TỬ CHO ĐỘNG CƠ MỘT CHIỀU

Abstract


Động cơ một chiều là một đối tượng điều khiển quan trọng do được ứng dụng rất rộng rãi cho nhiều lĩnh vực khác nhau. Vì vậy điều khiển động cơ một chiều được nhiều tác giả trên thế giới quan tâm, trong đó bộ điều khiển PI thường được sử dụng [17,19,20,21]. Bộ điều khiển mờ cũng được sử dụng  thay thế cho bộ điều khiển PI để đảm bảo tính mềm dẻo trong quá trình điều khiển. Tuy nhiên bộ điều khiển PI và bộ điều khiển mờ có nhược điểm thường tạo ra đáp ứng vượt qua điểm đặt quá cao và sai số xác lập lớn. Vì vậy mục tiêu đặt ra của bài báo là nghiên cứu khả năng thay thế bộ điều khiển PI và điều khiển mờ đối với động cơ một chiều bằng bộ điều khiển sử dụng đại số gia tử.  Qua đó thấy rõ hiệu quả của việc đưa đại số gia tử vào thiết kế các bộ điều khiển động cơ một chiều so với các bộ điều khiển truyền thống.
