中文摘要 | 本文研究一類整合了低高增益(low-and-high gain)與積分補償技巧的輸入受限控制器。研究顯示,在不明確的定值擾動下,只要這類控制器在高增益部分選擇充分大,便能達到輸出的漸近收斂目標,並確保系統的實用穩定性,不再需要以”極高”增益量方式來完成。除此之外本文證明,在有限時間後,受控狀態會進入終極限界區(region of ultimate boundedness)中的輸入不飽和子區域,並停留在內。因此可確保”輸入飽和現象”僅是這類整合型控制器的暫態行為。 |
英文摘要 | In this paper, we present a new approach that combines integral compensation and Low-and-high gain technique to develop a class of input-constraint controllers. Under constant disturbance, the approach shows an advantage of asymptotical regulation of the control state without using extremely high gain, and therefore the inherent chattering phenomenon can be effectively eliminated. Moreover, the proposed control can render the system state, after a finite time interval, staying within a residual set in which the control input becomes unsaturated. |
