poles and zeros 中文意思是什麼
-
The aircraft ' s longitudinal motion short period poles and long period zeros in right plan e may make the aircraft control system be not got by only using qft. so pole and zero assignment by state feedback is needed to change this circumstances and then qft is used to get the control system. simulink results are given to prove at the system meets the requirements.
飛機縱向運動方程的短周期和長周期的右半平面可能存在零極點對問題，這對飛機控製造成不利影響，直接利用定量反饋理論不能滿足要求。本次論文首先進行短周期狀態反饋極點配置，然後利用定量反饋來解決這個問題。通過模擬分析得到滿意的結果。 -
Abstract : this paper developed time domain integral constraints on error response for siso feedback control systems caused by nominal plant ' s near cancellation of stable pole - zero near the j - axis. these integral constraints should be satisfied by any feedback control systems. these integral constraints give new insight into the inherent trade - offs. it will result in the settling time longer or the infinite norm of the error response larger when there are near cancellations of stable pole - zero near the j - axis. hence, when feedback control systems are designed, it is necessary to avoid the compensator ' s poles and zeros nearly cancelling the nominal ' s zeros and poles ( even if these poles and zeros are stable )
文摘:導出了單輸入單輸出反饋控制系統誤差響應基於名義系統穩定的零、極點近似相消的時間域積分約束，此積分約束是任何反饋控制系統均應滿足的.這一約束給出了單輸入單輸出反饋系統固有折中的新的觀點.名義系統穩定的零、極點近似相消的存在導致反饋控制系統的調節時間延長或者誤差響應的無窮范數變大.因此，在反饋控制系統設計中，盡量避免補償器的零、極點與名義系統的極、零點近似相消（即使這些零、極點是穩定的） -
We will defer discussion of complex poles and zeros to a future article
我們會在其他文章中再談復雜的極點和零點。 -
The order - reduced results are verified by comparing the zeros, poles and outputs curves before and after the order reduction and applying the linear quadratic optimal control law for low - order model to the high - order model
通過零極點比較、輸出曲線比較和將針對低階模型設計的線性二次型最優控制律加入原高階模型等方法對降階結果進行了驗證。
