| 中文摘要 | 本文探討藉由離散量測下之連續非線性系統的電腦輔助控制設計問題。其架構是結合回饋線性方法及在提前一步預測範圍下建立,不過執行方式是不需要線上即時最適化演算。仰賴精確數値運算,明確控制律與高增益回饋效能可以強化輸出規則化表現。若併入非線性內在模式控制策略,則發展出電腦輔助下的輸出回饋控制。藉由數値模擬一放熱反應器系統內的組成控制,將提出控制方法與非線性模式預測控制做比較性評價。 |
| 英文摘要 | In this paper the problem of designing computer-assisted nonlinear control for continuously nonlinear systems with discrete measurements is addressed. Its framework allows one to establish the connections between the feedback linearization method and one-step-ahead prediction horizon, but its implementation does not require on-line optimization algorithms. Depending on the numerical calculation, the explicit control law with the high-gain feedback effect can reinforce the output regulation performance. Incorporating the nonlinear internal model control (IMC) strategy, the computer-assisted output feedback control is developed. Through numerical simulations on the composition control for an exothermic chemical reactor system, the comparative evaluation between the proposed control and the nonlinear model predictive control (NMPC) are given. |
