✦ Synopsis

This paper presents a sequel to the application of recursive filters to monitoring the vibrations of rotating machinery. The technique described in Part I (The Use of Non-stationary Recursive Filters) is further enhanced by using the angle domain. A combination of these techniques utilises the benefits and overcomes the limitations of both these approaches treated separately.

A number of computer simulations and experimental results demonstrate the ability of the new combined approach to provide an effective method for monitoring machinery operating under varying speed.

Varying speed machinery monitoring is fraught with difficulties due to non-stationary machine dynamics and vibrations. Most conventional signal processing methods based on digital sampling carried out in equal time intervals become inappropriate when monitoring the vibrations of varying speed machin
