Latest Patents

Raj M Bharadwaj holds a patent for a "Method and system for determining induction motor speed." This invention utilizes a non-linear, semi-parametric neural network-based adaptive filter to determine the dynamic speed of a rotating rotor within an induction motor. The system operates without the explicit use of a speed sensor, such as a tachometer. The neural network-based filter is developed using actual motor current measurements, voltage measurements, and nameplate information. It is trained using an estimated speed calculator derived from the actual current and voltage measurements. The filter employs voltage and current measurements to determine the instantaneous speed of the rotor and includes an on-line adaptation scheme that allows it to be readily adapted for new operating conditions during operations.
