Current computer-aided control system design environments seldom suppo
rt optimization methods for controller design in a truly interactive m
anner. A prototype tool, called PARSIM, supporting parallel processing
, optimization, and a graphical user interface is presented, addressin
g many of the problems inherent in current approaches to multiobjectiv
e optimization-based design methods. An XWindows interface is used to
simplify problem formulation and control the optimization processes. U
sing a previously developed interface, it is shown how the computation
al burden may be alleviated by parallel processing.
