System Identification of Classic HVDC Systems
SAIEE Africa Research Journal, 2011 Determining models from observations and studying the models' properties is essentially the functionality of science. Models attempt to link observations into some pattern. System identification is the art of building mathematical models of dynamic systems based on observed data from the systems.
