Abstract : A general development is given for the feedforward control scheme which minimizes the mean square error of the output deviation from target using a general linear transfer function model to characterize the process dynamics and a general autoregressive-integrated-moving-average model to characterize the disturbance. It is then shown by way of an example how the state variable models and the optimal control theory of papers one and two in this series can be used to design feedforward controllers which minimize the mean square error of the output deviations from target subject to constraints on the variances of the manipulated variables.
