  • Abstract
    In this paper, based on the analysis of H∞ controllers, an interesting and crucial observation concerning the structure of H∞ control systems is obtained. Due to this observation, closed-loop H∞ control systems can be clearly described as a disturbance estimator which is used to diminish the effect of exogenous input on the output. A clear representation of the feedforward-feedback structure of the H∞ controller is established
