Abstract

It is shown that complete design for a multivariable plant with unstructured additive uncertainty requires conforming of the plant model and controller, i.e. minimization of model uncertainty bound rated to the uncertainty bound, allowed by the controller for particular design specifications. A sample design procedure is developed using a SVD controller and quasi-normalization technique in order to re-solve a DC/AC convertor robust control problem
