불확실성을 갖는 단일입출력 시스템에 대한 TDC의 안정성/강인성 해석
Stability/Robustness of TDC for SISO Systems with Significant Unmodelled Dynamics
초록
Time Delay Control (TDC) method was proposed as a promising technique in the robust control area, where the plants have unknown dynamics with parameter variations and substantial disturbances are present. In this paper, based on the concepts of TDC, author propose a model reference control method for input/output model. The stability and robustness of the closed system has been analyzed for a class of linear time invarient (LTI) system. Then, in a simulation study, author's design method has been applied to a second order system, the result of which confirmed that the proposed control method performs satisfactorily as predicted.
