State-space controllers are difficult to implement in a distributed control system. Therefore a control design based on the common PID control structures is desirable. This article presents the… (More)
The tuning of advanced PID control structures for multi-variable plants is an important problem in industry. This paper discusses the parameterization of such control structures with a direct… (More)
Distillation columns show a highly nonlinear behavior. To design a satisfactory controller for the whole operating range using μ-synthesis, an uncertainty model representing column nonlinearity as… (More)
