To achieve this goal the controller must counteract in a suitable way the influence of disturbances.

Such expenditure is only justified if the demand for accuracy is too high to be met by analog computer circuitry involving operational amplifiers. An upper limit for the accuracy of this kind of circuit is in the order of 0.1%.
