<P> Informally , a controller designed for a particular set of parameters is said to be robust if it also works well under a different set of assumptions . High - gain feedback is a simple example of a robust control method ; with sufficiently high gain , the effect of any parameter variations will be negligible . From the closed loop transfer function perspective , high open loop gain leads to substantial disturbance rejection in the face of system parameter uncertainty . </P>
