PD/PID controller tuning based on model approximations: Model reduction of some unstable and higher order nonlinear models

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. Numerou...
