VISUALIZATION OF INPUT-OUTPUT RELATION OF SISO/MIMO SYSTEMS USING PARAMETRIZATION OF TWO-STAGE COMPENSATOR DESIGN

摘要

In this paper, we consider the two-stage compensator designs for single-input and single-output (SISO) plants and multi-input and multi-output (MIMO) plants in the frame-work of the factorization approach. Recently, one of the authors has given the parametrization of stabilizing controllers given by the two-stage compensator design. As an investigation of the role of the two-stage compensator designs, we implement two visualization systems of the parametrization of stabilizing controllers based on the two-stage compensator design. One is animation system. The other is three-dimensional (3D) graph system. These systems display input-output relationship and norms of signals. Based on the two-stage compensator designs, we have implemented the system in which the outputs are shown by the animation system and the 3D graph system. On the other hand, the input signals can be visualized two-dimensional (2D) graphs. Further, the norms of signals can also be visualized in 2D graphs. As a model of the factor-ization approach, we have employed the discrete-time LTI systems.
