Abstract :
Considers design of feedback controllers for spatially distributed processes. A constructive design approach is developed based on two-dimensional loopshaping concepts. The closed-loop response of the system is modified through the design of an H2 optimization problem in terms of spatial and dynamical frequencies. The conflicting objectives of disturbance attenuation and robust stability are traded off in the design of a low-order localized feedback controller. The proposed design technique is illustrated using an industrial control example taken from the papermaking industry
