Method for adjusting a system that is modified in a cycle to a non-constant cyclical target profile and controller therefor

1. A method for adjusting a system that changes in a cycle to a nonconstant cyclic target profile, comprising:

comparing measured actual values (E) with appropriate target values (R) for the target profile;

outputting a control value (A), wherein the target profile is divided into a prescribed number of time periods,

prescribing a target value (R) for each time period;

determining a current actual value (E) for each time period; and

separately executing a control using a dedicated signal controller for each time period based on the target value (R) and the actual value (E).

2. The method of claim 1 , wherein each signal controller includes dedicated parameterization (Kp, Ti, Td) of the control factors (P, I, D).

3. The method of claim 1 , including the step of outputting the controller values (A) as a control profile at the end of a cycle.

4. The method of claim 1 , wherein the signal controllers are PID controllers.

5. The method of claim 1 , wherein the signal controllers are digital signal controllers.

6. The method of claim 1 , wherein the executing step is used for controlling the load placed on a prosthesis by a testing machine.

7. The method of claim 1 , wherein the executing step is used for controlling the load placed on an artificial foot.

8. A controller for a system that changes, in a cycle, to a nonconstant target profile comprising:

a plurality of signal controllers;

a control circuit which divides the cycle into sections corresponding to the number of signal controllers and assigns each single controller a prescribed target value (R) and a measured actual value (E); and

an output arrangement for the controller values (A) generated by the signal controllers.

9. The controller of claim 8 , wherein the output arrangement is configured to output an output profile which is formed from the controller values (A) at the end of a cycle.

10. The controller of claim 8 , wherein the signal controllers are individually parameterizable using control parameters (Kp, Ti, Td).

11. The controller of claim 8 , wherein the signal controllers are digital controllers.

12. The controller of claim 8 , wherein the signal controllers are PID controllers.

13. The controller of claim 8 , wherein the output controller values (A) can be supplied to a control device for the placement of a load on a prosthesis by a testing machine.

14. The controller of claim 13 , wherein the testing machine is designed for the loads placed on an artificial foot.
