| 1. |
Used for control applications. |
Used for Analysis applications. |
| 2. |
Model is used for controller design. |
Model is used for offline simulation of systems. |
| 3. |
Compact and easy to manipulate model. |
Free run simulation without access to past output measurement. |
| 4. |
Output prediction with little computational burden. |
No access to prediction. |
| 5. |
One step prediction. |
No means to reconstruct. |
| 6. |
Correction at each step. |
Model must be entirely deterministic. |
| 7. |
Initial model need not be very accurate. |
Should be more accurate than online. |
| 8. |
|
Complexity may be high. |
