This paper extends the results obtained in previous work on design of feedforward control in the presence of uncertainties. Two alternative designs are compared for the rejection of a specific mesasurable disturbance: a design based on feedback compensation alone and a second design combining both feedback and feedforward action. Extension of parametric ranges of the study provide additional insight into the trade-off between achievable performance and increasing controller so-phistication.
