positive feedback loop 中文意思是什麼
positive feedback loop
解釋
正反饋迴路-
In this positive feedback loop, european revolutions like the glorious revolution ( 1688 ) or the french revolution ( 1789 - 1793 ) give the institutional changes a further push. and in this way, the efficient institutions were established and the outstanding economic growth performance achieved
當這種「積累效應」形成一定氣候時，便可能促發像「光榮革命」和法國大革命那樣的政治變革；並通過此等「基因突變」的方式使制度的優勢進一步擴大。 -
At first, the robust h control for uncertain nonlinear systems with norm bounded uncertainties is studied, based on a positive definite solution of hamilton - jacobi - issacs inequality ( hji ), a sufficient condition is given such that the closed loop system is asymptotically stable and its l2 - gain is less than or equal to a prescribed value. using this condition state feedback control law and an output feedback control law which ensured robust hx performance of the closed - loop system are derived. due to the difficulty to solve hji, a method is proposed which do not require solving it by using an appropriate lyapunov function
首先，研究了范數有界型不確定非線性系統魯棒h _控制問題，基於hamilton - jacobi - issacs不等式（ hji ） ，給出了閉環系統漸近穩定且l _ 2 -增益有限的狀態反饋和輸出反饋設計演算法。考慮求解hji的困難性，針對不確定非線性系統，通過適當地選擇lyapunov函數，提出了求解非線性系統魯棒h _控制問題的演算法，可以避免求解hji 。 -
This expelled methane increases temperatures and releases more methane, creating a positive feedback loop
這些甲烷會進一步提高溫度然後又釋放更多的甲烷，形成一個惡性循環。
