英文摘要 | 針對離散時間的模型追蹤系統,本文設計一種可變結構控制器,使得系統之工 (plant) 之狀態輸出與理想模型 (model) 之狀態輸出的誤差響應以滑動模式之軌跡態穩定 趨進原點。此控制器包含兩部份,一為滑動控制,設計滑動面,使得誤差狀態的滑動模式是 穩定的且誤差狀態將滑進原點;另一部份為趨近控制,設計控制器使得誤差狀態能快速趨近 滑動面。此外,本文也指出此系統中之滑動面實際上將擴張成一個滑動區域,此區域乃由對 角化轉換矩陣來決定。值得一提的是,設計出來之趨近控制器之增益是一個內部元素均相等 之簡單向量,這將使得實際控制器更容易被實現。 f the matrix G for the sliding surface such that the sliding mode is stable; the other isthe reaching control which is designed to force the error state approching the sliding surface. It is also shown that in this controlled system the sliding surface is extended to a sliding region which is determined by a diagonalizing transformation matrix. Furthermore, the designed reaching control gain is a simple vector with the same elements. This may make the practical controller be easily implemented. |
