1. A method comprising: identifying multiple model structure-model order combinations, the model structure-model order combinations associated with a process to be controlled; determining one or more metrics for each of the model structure-model order combinations; selecting at least one of the model structure-model order combinations based on the one or more metrics; and providing a final model for controlling the process, the final model based on the at least one selected model structure-model order combination; wherein identifying the model structure-model order combinations comprises identifying multiple model sets, each model set comprising multiple models associated with a single model structure and having different model orders, different model sets associated with different types of model structures.
