| Research Abstract |
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.
