Design Method of New Adaptive Control Systems based on IQC and Its Application for Time-Varying Delayed Communication Systems

一年来的研究成果如下：(1)建立了与现有系统相适应的实时时滞在线辨识方法，为时变通信时滞系统的新型自适应控制系统的控制设计提供了理论依据。该辨识方法包括带有纯滞后估计的自适应观测器模型和基于凸优化问题的调节律。该方法成功地同时估计了通信系统的实时时延、未知集中参数和状态变量。特别值得注意的是，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)与(1)中的状态一样，只提供了一种建立通信系统辨识问题的方法，而对控制系统的开发是一项重大任务。新的控制方法显示了仿射非线性系统在存在未知确定性扰动和固定时滞时的全局调节。这种控制方法的特点如下。利用内模原理实现了时滞的补偿。提出了一种新的监督控制器来控制具有IQC要求的时延和建模误差的通信系统，并发表了6篇关于上述结果的文章。达到了最初的目的。

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.
