Abstract :
In this note, we consider SISO plant families with affine parameter uncertainties in the numerator and denominator of their transfer function. It is assumed that the controller has been chosen, and a bound on sensitivity is given. For a nominal plant satisfying the performance criteria we provide a formula for the maximal allowable perturbations of the parameters maintaining the performance criteria
