An apparatus for controlling a two degree of freedom process comprises a first controller, a second controller, and a process model. The three components are oriented in such a way that the first controller receives input from a first variable and the second controller receives input from a second variable. The process model is a model of the process process and provides feedback to the first controller. Furthermore, the orientation of the controllers isolates the first controller from the second variable and isolates the second controller from the first variable when the process model matches the process. Since each controller shapes a response to only one variable, the transfer functions of each controller can be chosen to meet stringent performance standards.
