Sammendrag
A model reduction technique based on optimization theory is presented, where a possible higher order
system/model is approximated with an unstable DIPTD model by using only step response data. The
DIPTD model is used to tune PD/PID controllers for the underlying possible higher order system. Numerous
examples are used to illustrate the theory, i.e. both linear and nonlinear models. The Pareto
Optimal controller is used as a reference controller
