| 1 | Online-SVR-compensated nonlinear generalized predictive control for hypersonic vehicles显示文摘This paper is concerned with the problem of hypersonic vehicle (HSV) attitude control system in uncertain flight conditions. The problem can be expressed as the adaptive robust control for a class of uncertain nonlinear systems. Based on the description of the aerodynamic structure and the model of flight control system of a certain kind of HSV, the ideal nonlinear generalized predictive control (NGPC) law based on uncertain nonlinear model is raised first to optimize the receding-horizon criterion of tracking errors. Then the online support vector regression (SVR) is employed to identify the uncertain item in the ideal control law. It is the compensating part of the controller. In addition, the stability of the close-loop system is analyzed using the Lyapunov method. The developed control strategy is well-implemented in this HSV attitude control system, and the simulation results compared with both nominal NGPC and RBF neural network disturbance observer show the good robustness and disturbance attenuation ability of this strategy and demonstrate the efficiency of online SVR algorithm. | CHENG Lu JIANG ChangSheng PU Ming | 2011 | Science China(Information Sciences)2011，54，3： | 17 |

| 6 | ASYMPTOTIC STABILITY OF RETARDED FUNCTIONAL DIFFERENTIAL EQUATIONS BY LYAPUNOV’ DIRECT METHOD显示文摘This paper is devoted to studying the asymptotic stability of retarded nonlinear functional differential equations by the method of Lyapunov functionals. Under the as-sumption that there exists a positive definite time-invariant Lyapunov functional with negative semi-definite derivative, we focus on the extra conditions to guarantee the asymptotic stability, and present a new criterion, which is less conservative than the classical one. Finally, an example is given to illustrate the effectiveness of the result. | Lipo Mo (School of Computer and Information Engineering, Beijing Technology and Business University, Beijing 100048 Key Laboratory of Math., Informatics and Behavioral Semantics, Ministry of Education, School of Math. and Systems Science, Beihang University (BUAA), Beijing 100083) | 2010 | Annals of Differential Equations2010，26，3： | 0 |
