A Multivariable Toolbox for use with Matlab

We describe a new Toolbox for the frequency-domain analysis and design of multivariable feedback systems, to be used with PC-Matlab or Pro-Matlab. The principal model representations employed by the Toolbox are first described. Its capabilities are then illustrated by a worked design example, which shows the use of a Nyquist Array method. Finally, other design techniques supported by the Toolbox are briefly reviewed.
