Fast Output Sampling Feedback with Two Delayed Inputs for MIMO System

摘要

In modified fast output sampling (FOS) feedback approach system states are estimated from the observations of previous outputs and an input. In this paper, a FOS scheme utilizing feedback of past outputs and two past inputs is proposed for multi-input multi-output (MIMO) system. It is shown that the addition of one more past input in the feedback results in improvement in the closed-loop system performance. The devised technique is examined for linear and nonlinear MIMO systems. For comparison purpose simulation results are generated using both modified FOS and proposed methods and it is observed that, the performance of suggested control technique is superior to former.
