Abstract: A new method of order tracking of rotating machinery based
on instantaneous frequency estimation (IFE), is proposed. Compared with
traditional methods of order tracking, this method takes some
outstanding advantages, for example, hardware simplified, which required
by order analysis and only software depended for order tracking. The
simulations and actual test testify the validity of the method. The
algorithms of the tracking and estimation about the instantaneous speed
of reference shaft are programmed. This method is an effective
supplement to traditional order tracking methods and specially satisfied
the requirement of virtual instruments.
