Influence of magnitude of interaction on control in decentralized adaptive control of two input two output systems

Abstract

This paper presents an analysis of the influence of interactions on the course of the control process using the chosen method of decentralized adaptive control of two input two output systems. In the paper, after the general introduction to decentralized and adaptive control, the necessary theoretical framework is presented. In this chapter, there is described the method used for decentralized control, the method of identifying the system parameters and the method of calculating the parameters of the controller. In the examples, the effect of the change in the gain of the interaction transfer function in one branch and the effect of the change in the gain of the interaction transfer functions in both branches were tested. Furthermore, it was verified that the change of the pole value in the interaction in one branch influences the control, and the effect of the change of the pole value in the transfer functions of the interaction in both branches. The results of these verifications are presented on selected examples and finally their evaluation is performed.
