Abstract

A Method and apparatus for monitoring and controlling appliances and systems having a two-dimensional or multidimensional operating envelope. A map of the operating envelope or of a part of it onto a unit domain or the operating envelope of another appliance is used for monitoring and control. The apparatus produces this map. The method and the apparatus allow monitoring and control which can be carried out substantially in the same way for appliances whose operating envelopes have different shapes.

Claims

1. A method for controlling at least one appliance having a first operating range that is multidimensional, said method comprising steps of:

mapping at least a part of the first operating range onto a second operating range of another appliance; and

transforming a first operating point in the first operating range by a map to a second operating point in the second operating range of the another appliance for control.

2. The method as claimed in claim 1, wherein at least one process parameter is determined by the map.

3. The method as claimed in claim 1, further comprising:

determining the first operating point in the first operating range;

transforming the first operating point by a stored map rule for the map; and

outputting co-ordinates of the second operating point.

4. The method as claimed in claim 1, further comprising:

determining the first operating point in the first operating range;

transforming the first operating point by a stored map rule for the map;

determining parameters which define a control action, based on the co-ordinates of the second operating point; and

carrying out the control action.

5. The method as claimed in claim 1, wherein the first operating range is two-dimensional, and wherein the mapping step maps a polygon, which is similar to the first operating range, onto the second operating range of the another appliance.

6. The method as claimed in claim 1, wherein at least one process parameter is determined by an inverse transformation with respect to the map.

7. An apparatus for controlling at least one appliance, each of said at least one appliance having a first operating range that is multidimensional, said apparatus comprising:

means for determining and storing parameters required to produce a map which maps at least part of the first operating range and an operating point in the first operating range into a second operating range of another appliance;

means for producing the map;

means for outputting coordinates of an image of the operating point; and

means for carrying out a control action.

8. The apparatus as claimed in claim 7, further comprising means for producing the map for any point in the first operating range.

9. The apparatus as claimed in claim 7, further comprising means for comparing images of two points located in the first operating range, with the comparison being carried out in the second operating range of the another appliance.

10. The apparatus as claimed in claim 7, further comprising means for comparing an image of a point located in the first operating range with at least one line in the second operating range of the another appliance.

11. The apparatus as claimed in claim 7, comprising means for determining at least one process parameter by the map of the first operating range onto the second operating range of the another appliance.

12. The apparatus as claimed in claim 7, further comprising:

a first computation module for transformation of a set point to a transformed set point in the second operating range of the another appliance;

a measuring unit for determining a position of the operating point;

a second computation module for transformation of the operating point to a transformed operating point in the second operating range of the another appliance;

a comparison unit for comparison of the transformed operating point with the transformed set point or with at least one control line of the second operating range;

a monitoring unit for determining parameters required for control; and

an execution unit for carrying out operations required for control.

13. A method for controlling at least one appliance having an operating range that is multidimensional, said method comprising steps of:

mapping at least a part of the operating range onto a unit domain; and

transforming a first operating point in the operating range by a map to a second operating point in the unit domain for control.

14. The method as claimed in claim 13, wherein at least one process parameter is determined by the map.

15. The method as claimed in claim 13, further comprising:

determining the first operating point in the operating range;

transforming the first operating point by a stored map rule for the map; and

outputting co-ordinates of the second operating point.

16. The method as claimed in claim 13, further comprising:

determining the first operating point in the operating range;

transforming the first operating point by a stored map rule for the map;

determining parameters which define a control action, based on the co-ordinates of the second operating point; and

carrying out the control action.

17. The method as claimed in claim 13, wherein the operating range is two-dimensional, and wherein the mapping step maps a polygon, which is similar to the operating range, onto the unit domain.

18. The method as claimed in claim 13, wherein at least one process parameter is determined by an inverse transformation with respect to the map.

19. An apparatus for controlling at least one appliance, each of said at least one appliance having a multidimensional operating range, said apparatus comprising:

means for determining and storing parameters required to produce a map which maps at least part of the operating range and an operating point in the operating range into a unit domain;

means for producing the map;

means for outputting coordinates of an image of the operating point; and

means for carrying out a control action.

20. The apparatus as claimed in claim 19, further comprising means for producing the map for any point in the operating range.

21. The apparatus as claimed in claim 19, further comprising means for comparing images of two points located in the operating range, with the comparison being carried out in the unit domain.

23. The apparatus as claimed in claim 19, further comprising means for determining at least one process parameter by the map of the operating range onto the unit domain.

24. The apparatus as claimed in claim 19, further comprising:

a first computation module for transformation of a set point to a transformed set point in the unit domain;

a measuring unit for determining a position of the operating point;

a second computation module for transformation of the operating point to a transformed operating point in the unit domain;

a comparison unit for comparison of the transformed operating point with the transformed set point or with at least one control line of the unit domain;

a monitoring unit for determining parameters required for control; and
