Changing the amplitude of a connector force during a simulation depending on a measured rotation

Hello, 

I would have a question. I've got a model in Abaqus which can be controlled by defining the three rotations or by defining external forces. I need to simulate one given movement by only defining the right amplitudes of external forces. So by using all external forces, the given movement should be approximated. My question is: Is there a function in abaqus, where I can change the amplitude of a connector force depending on a measured rotation during the simulation?

Thank in advance for any help!
