Fixed-bandwidth correlation window method and system for a self-balancing rotatable apparatus

A method for dynamically balancing a rotating system by collecting and correlating data from said rotating system, wherein said rotating system contains sensors therein, said method comprising the steps of:

• sampling data from said sensors to obtain a select time span of said data, wherein sampled data contains information indicative of the dynamics of said rotating system, such that said select time span is of sufficient size to extract signal components of interest and attenuate low frequency modulations associated with said rotating system;
• adjusting said select time span of said data according a nearest number of full revolutions of said rotating system just exceeding said select time span;
• processing said select time span of said sampled data to extract said signal components of interest and provide balance measures used to assess balance conditions and characterize control models and impact a course of balancing corrections necessary to dynamically place said rotating system in a balanced state;
• and
• collecting a fixed number of samples per revolution of said data independent of a rotational speed of said rotating system.
