Claim 16:
17. The system of claim 16 wherein:
the drilling domain applications include:
a first algorithm to mitigate stick-slip occurrence during drilling; and
a second algorithm to automatically control drilling;

the control signals are first control signals;
the actuator is a first VFD;
the component is a top drive driven by operation of the first VFD;
the system further comprises:
a second VFD operable to change an operational parameter of a drawworks; and
a third controller configured for communicating second control signals to the second VFD to control the second VFD and thereby control operation of the drawworks; and

the second controller is also connected between the third controller and the second VFD and is operable to alter the second control signals.
