NOUS: a MATLAB toolbox for the design of nonovershooting and nonundershooting multivariable tracking controllers. Recently Schmid and Ntogramatzidis [1]-[2] gave a design method for linear time invariant state feedback controller to avoid overshoot and undershoot in the step response for multivariable systems. In this paper we describe a new public-domain MATLAB toolbox to implement this control scheme.
