中文摘要
      研究了一类时滞依赖型线性中立系统的观测器的设计与镇定问题,首先建立了一个时滞依赖型稳定性准则,基于LMI正定解的存在性,给出确保误差动力系统渐近稳定的充分条件及经状态反馈而达到镇定的设计方案.最后通过数值仿真来说明本文所得结论的正确性和有效性.
英文摘要
      The delay-dependent stability criterion,the state observers design and observer-based stabilization are dealt with for linear neutral delay systems.Firstly,a delay-dependent stability criterion is developed based on a method of linear matrix inequality(LMI).Secondly,an LMI-based observer design for the error dynamics is presented.Thirdly,the observer-based stabilization problem of the neutral delay systems is solved by means of the solvability of two LMIs.Finally,two numerical examples are used to demonstrate the validity and effectiveness of the proposed approaches.
