Abstract
Apparatus for detecting an operating condition of a machine synchronizes sampling instants with the machine condition so that high reliability data are obtained. More particularly, an indication of the operating condition of a rotor of the machine is developed at each sampling instant. The operating condition may be, for example, the position of the rotor, in which case estimates of the rotor position and rotor velocity at each of the sampling instants are developed. Sampling signals are then derived from the rotor position and velocity estimates to synchronize the sampling instants to the rotor position.
