Abstract :
It is shown that the control system with disturbance observers has a nice property of disturbance rejection even without an integral action in the controller if the controlled process has an integration. This paper is concerned with a robust control design using H/sub /spl infin// optimality theory when the controlled process is subject to model uncertainties, in which the conditions of robust stability and stability guaranteed control system are presented.<>
