Pressure-flow networks are inherently multivariable, coupled and nonlinear systems that are not straightforward handled by conventional PID controllers. In this work, we analyze the control problem for a steam distribution network in the framework of a recent proposed method, that gives linearization and decoupling, together with a systematic design for nonlinear feedforward control for perfect disturbance rejection.
