Study result of the last year is shown as follows.(1) The identification method for the real time-delay with on-line manner has established as the procedure which coped with existing system in order to show control design theory of new adaptive control systems for time-varying communication delay systems. This identification method consists of the both adaptive observer with dead time estimation-model and the adjusting law based on convexity optimization problem. It was successful to estimate the real time-delay, unknown lumped parameter and the state-variables of the communication systems simultaneously. In particular, it is note that the stability of total system can be guaranteed by using the Lyapunov function derived from IQC theory.(2) As state in (1), only a method of forming as identification problem of communication system was provided, and development to control system was one of big assignment. The new control method show the global regulation for the affine nonlinear systems in the presence of unknown deterministic disturbance and fixed time-delay. The characteristic of this control method is the following. The compensation of time-delay is achieved by using the internal model principle. The parallel compensator is arranged in order to establish the stability and passivity.(3) The new supervisor controller was proposed for control the total communication systems with time-delay and modelling error satisfied IQC.So six article about above-mentioned result was published. The original purpose achieved.

去年的研究结果如下：(1)建立了实时时延在线辨识方法，作为对已有系统的处理过程，以展示时变通信时延系统自适应控制系统的控制设计理论。该辨识方法由带死区估计模型的自适应观测器和基于凸性优化问题的调节律两部分组成。成功地同时估计了通信系统的实时时延、未知集总参数和状态变量。特别要注意的是，利用由IQC理论导出的Lyapunov函数可以保证整个系统的稳定性。(2)如(1)所述，仅提供了一种形成通信系统识别问题的方法，对控制系统的开发是一项重大任务。该控制方法对存在未知确定性扰动和固定时滞的仿射非线性系统具有全局可调性。这种控制方法的特点是：利用内模原理实现了对时滞的补偿。为了保证系统的稳定性和无源性，设计了并联补偿器。(3)提出了一种新的监督控制器，用于控制满足IQC的具有时延和建模误差的全部通信系统。因此发表了六篇关于上述结果的文章。达到了最初的目的。
