The delta operator is an alternative to the shift operator commonly used for representation of sampled-data systems. It has a number of well-known conceptual and numerical advantages and some very convenient implications of its use in identification are also well described. This MSc project consists of applying IFT in controllers described with the delta operator. [...]
In DD control design, once the reference model has been chosen the design follows a well specified algorithm, and thus is completely automated. The choice of reference model must express mathematically either one or some combination of the various control objectives (noise rejection, reference tracking performance, robustness, etc). In order to make a fully automated controller [...]
Many processes behave like a linear dynamic model with a nonlinear static map at its input (in which case the process is referred to as a Hammerstein system) or at its output (resp. a Wiener system). It is standard industrial practice to mitigate the effects of this nonlinear element by the incorporation of its approximate [...]
