To get a closer dynamic behavior of the real system  both the flexible manipulator linkage and the actuator dynamics are considered. The exact dynamic model of flexible manipulator is derived using Lagrange principle and assumed modes method. The partial decoupled dynamic equation is derived using nonlinear decoupling feedback control method. The whole dynamic model is established by a driven Jacobin matrix  which represents the coupling between hydraulic servo system and mechanical system. A variable structure controller with inverse dynamics is designed for trajectory tracking. To weaken the chattering of control signal  saturation function is used to instead of sign function. The experimental results investigate the effectiveness of the proposed approaches. 2012 IEEE.   A NEW TRUST-REGION ALGORITHM FOR NONLINEAR CONSTRAINED OPTIMIZATION 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2010, 卷号: 28, 期号: 1, 页码: 72-86 作者:  Niu, Lingfeng;  Yuan, Yaxiang   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/07/30 Trust region method  Augmented Lagrange function  Filter method  active set   On the use of simplex methods in constructing quadratic models 期刊论文  OAI收割 SCIENCE IN CHINA SERIES A-MATHEMATICS, 2007, 卷号: 50, 期号: 7, 页码: 913-924 作者:  Zhou, Qing-hua   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 unconstrained optimization  trust region method  quadratic model  Lagrange function  simplex methods  direct methods   On weighted Lebesgue function type sums 期刊论文  OAI收割 JOURNAL OF APPROXIMATION THEORY, 2007, 卷号: 146, 期号: 2, 页码: 243-251 作者:  Shi, Ying Guang   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 weighted Lebesgue function type sum  Lagrange interpolation  orthogonal polynomials
