There are three sections in this paper. the first section : we consider the initial boundary value problem on half line and bounded interval, with kato ' s method for abstract quasi - linear evolution equations and a prior estimates of. solution, we get the existence of global smooth solution and the blow - up of solution in finite time under some conditions
第一部分：考慮了camassa ? holm方程在半無界和有界區域上的初邊值問題，用kato關于擬線性演化方程的初值問題的理論及先驗估計的方法，證明了整體解的存在性，及在一定條件下，解在有限時間內的blow ? up 。 -
The result can be used in control problems whether the time interval is finite or infinite, the control set is bounded or unbounded, and also for systems with a weak differentiable function, i. e., the function f is only strong continuously g - differentiable but not f - differentiable. so, th 6. 2. 7 is a uniform theory of optimal control, and it has wide - ranging applications
可以看到，我們的結11摘要果可用於有限時域和無限時域、有界控制和無界控制、並且對系統中函數f的可微性要求也有較大的減弱? f對狀態變量x可以是僅有強連續的g一導數、不要求為f一可微。 -
When impact applies on a discrete system in which one of constraints is a constant with coulomb friction, the phenomenon of slip - stick at the point can cause the change of friction and the integration for frictional force during infinitesimal impulsive interval becomes impossible according to traditional impulsive dynamics of discrete systems. by introducing a new dimensional time parameter, first - order momentum - impulse differential equations are obtained and the discussion over infinitesimal impulsive interval is transformed into a piece - wise study on the finite region of impulse
在引入新的無量綱的時間參數后，通過建立相應的動量-沖量的一階微分方程，在趨近於零的沖擊區間的討論變為在有限區間中來分段研究含滑動-黏滯的沖擊過程，得到了受到多點打擊的離散系統考慮庫侖摩擦時的動力學的求解方法，即根據沖擊前的初始狀態無需回到繁瑣的微分方程的求解便可以得到沖擊后系統的動力學響應。 -
Abstract : iterative learning control is an effective approach to the control of processes that are repetitive in nature. in this paper, an open - closed - loop pi - type iterative learning control scheme for the precise tracking control of a class of discrete nonlinear time - varying systems over a finite time interval is presented. the scheme updates control input with tracking errors of both current and last iterations simultaneously. sufficient and necessary conditions which guarantee the convergence of the scheme are given and then proved with inductive method. finally, the conditions are verified with simulation results
文摘:對于具有重復運動性質的對象，迭代學習控制是一種有效的控制方法.針對一類離散非線性時變系統在有限時域上的精確軌跡跟蹤問題，提出了一種開閉環pi型迭代學習控制律.這種迭代律同時利用系統當前的跟蹤誤差和前次迭代控制的跟蹤誤差修正控製作用.給出了所提出的學習控制律收斂的充分必要條件，並採用歸納法進行了證明.最後用模擬結果對收斂條件進行了驗證
