Method and system for determining induction motor speed

A computer program product residing on a computer usable medium for determining the speed of a rotating rotor within a motor, said computer program product comprising:

• program code means for implementing a neural network-based adaptive filter;
• program code means for generating a set of filter parameters for said neural network-based adaptive filter with respect to said motor before operation of said motor;
• program code means for measuring present and past current values along with present and past voltage values for one or more phases of said motor during operation;
• and
• program code means for determining a rotating speed of a rotating rotor within said motor during operation using said measured present and past current values along with said measured present and past voltage values of said motor via said neural network-based adaptive filter in conjunction with said set of filter parameters.
