About Compensators
Compensators are control techniques that improve the tracking and accuracy of
your controller. They play an important role in optimizing system performance.
Various compensators are available to suit specific test requirements.
Null Pacing
Null pacing ensures that desired levels are achieved on the initial command pass
without over programming the input.
Null pacing provides the following benefits:
• Works with cyclic or random profiles
• Works with linear or non-linear specimens
• Optimizes performance to reproduce wave shape or to maximum test speed
without regard for wave shape
Null pacing is typically used in tests in which the wave shape is not important,
and you want to complete the test as quickly as possible while meeting every
peak within the specified tolerance. Null pacing can adjust the speed of the
command, using maximum performance of the mechanical system. It is also used
in tests in which every peak must be achieved within a specified tolerance, but
overshooting cannot be tolerated.
