CLAIMS

1 . A method for controlling a process, the method comprising an

adaptive control model and at least one process input and at least one process output, the control model comprising:

- predicting the relevant targets in the process; characterized in that

- the relevant drivers for the process being selected based said target prediction.

2. A method according to claim 1, where the method comprising

adapting a number of parameters based on one or more inputs, and using the adapted parameters as an input for the target prediction.

3. A method according to claim 1 or 2, where the method comprises manipulated input variables, dependent output variables, non- manipulated input variables and performance goal and measures.

4. A method according to any of the preceding claims, where the

method comprises non-linear parameter adaptation, target

prediction, target tuning, driver tuning and driver selection as input to the process to be controlled.

5. A Method according to claim 4, where the manipulated input

variables and the dependent output variables are used for the non- linear parameter adaptation and further for the target prediction together with the output from the non-linear parameter adaptation.

6. A method according to claim 5, where the non-manipulated input variables and performance goal and measures are used for the target tuning.

7. A method according to claim 6, where the method comprises measuring an offline parameter and providing the offline parameter measurement as an input for the target tuning.

8. A method according to claim 6 or 7, where the target prediction and the target tuning is used for the driver tuning.

9. A method according to any of the preceding claims, where the

method comprises a preprocessing unit for preparing the input signals for the adaptation process.

10. A control system adapted to perform the method according to

the preceding claims in relation to a production apparatus.

11. A production apparatus comprising a control system exercising a method according to any of the preceding claims.

12. A production apparatus according to claim 11, where the apparatus comprises measurement devices for measuring manipulated data in the process as well as non-manipulated data in and/or around the process and where the data are fed to the control system.
