Notes:
A class of dynamic model approximation techniques based on a frequency domain Taylor series expansion is presented. These methods yield low-order models and are analytical rather than computational in nature; that is, one can retain important parameters (which may be time varying) from the original model in functional form in the low-order model. This feature is very attractive for on-line updating of the simplified model and subsequent control of the process. An example for a tenth-order original model has shown that the analytical low-order models provide excellent approximations to the step response of the original system.
