| 1 | A version of Hill's lemma for Cosserat continuum显示文摘根据希尔为古典 Cauchy 连续统的词根,希尔为异构的 Cosserat 连续统当模特儿的微宏 homogenization 的词根的一个版本在平均地的理论的框架被介绍。要求为建模在代表性的卷元素上规定的可被考虑的边界条件被提取并且讨论了保证希尔晓东精力状况和一阶的平均领域理论的满足。 | Xikui Li Qipeng Liu | 2009 | Acta Mechanica Sinica2009，25，4： | 3 |
| 2 | Infinite horizon indefinite stochastic linear quadratic control for discrete-time systems显示文摘This paper discusses discrete-time stochastic linear quadratic(LQ)problem in the infinite horizon with state and control dependent noise,where the weighting matrices in the cost function are assumed to be indefinite.The problem gives rise to a generalized algebraic Riccati equation(GARE)that involves equality and inequality constraints.The well-posedness of the indefinite LQ problem is shown to be equivalent to the feasibility of a linear matrix inequality(LMI).Moreover,the existence of a stabilizing solution to the GARE is equivalent to the attainability of the LQ problem.All the optimal controls are obtained in terms of the solution to the GARE.Finally,we give an LMI-based approach to solve the GARE via a semidefinite programming. | Weihai ZHANG Yan LI Xikui LIU | 2015 | Control Theory and Technology2015，13，3： | 2 |
