H/sub /spl infin// controller design from pulse response data

For linear systems, the dynamic characteristics can be represented either by input-output data such as frequency characteristics and impulse responses or models with finite number of parameters. Previous optimal control system design has been done for parametric models such as the state space equation or transfer function. The construction of such parametric models always includes errors, so the direct design of the controller from the pulse response may avoid the concern about the modelling error. The paper presents H/sub /spl infin// output feedback controller design from the pulse response.
