What is the difference between Transfer Function Model and Process Model
显示 更早的评论
Estimating Transfer Function Models for a Heat Exchanger - MATLAB & Simulink Example (mathworks.com)
In this Example, it use transfer function with a time delay as model to do the estimation(section"Transfer Function Estimation from an Initial System"). Next section "Process Model Estimation", it improve the estimation by using a process model.
However, the two models have the same structure, why do them conduct a different result ?

Hi,
Here are the difference between Transfer Function Model and Process Model:
- Model Structure and Assumptions: The initial transfer function model is more generic, while the process model is tailored to specific physical and operational characteristics of the heat exchanger.
- Estimation Techniques and Criteria: Different optimization algorithms and error metrics may be used in estimating the two models, leading to variations in how well each model fits the observed data.
- Data and Information Utilized: The process model might leverage the same data more effectively by incorporating assumptions about the system's physical behavior.
- Parameterization and Flexibility: Process models allow for detailed parameterization that captures specific dynamics of the system, potentially leading to a better fit and more accurate predictions.
- Computational Approach: The algorithms and strategies for estimating the process model may be more sophisticated or targeted, utilizing additional knowledge about the system to achieve a more accurate model.

Hope it helps.
