Method for obtaining information on the phase of a rotating system based on determination of the fundamental component of an incoming signal provided by a sensor driven by a periodic modulation function and device for controlling a rotating system
Abstract:
Phase information of a rotation system is obtained by a) reading the present output value Sk, (k=0, . . . , N−1) of the sensor at a sequence of N points of time during a first period of a periodic modulation function (PHA,PHB,PHC, PHD), b) storing read output values Sk or a value derived from this output value at least temporarily in a memory, c) extracting information on the phase of the rotating system, wherein said information is extracted based on evaluation of a function of the type, wherein=and, and d) sampling and storing sequentially further output values Sk, k=N,N+1, . . . of the sensor at corresponding points of time in the following periods of the periodic modulation function (PHA,PHB,PHC, PHD). Each reading information on the phase of the rotating system based on the function is extracted and a controller device (100) for application of this technique.
