Abstract
A new method of order tracking of rotating machinery based on instantaneous frequency estimation (IFE) is proposed in this paper. Compared with traditional methods of order tracking, this method has some outstanding advantages, such as hardware simplified, which is required by order analysis, and only software depended for order tracking. The simulations and actual tests 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 satisfies the requirement of Virtual Instruments (VI).
