MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202631107939 A) filed by National Institute Of Technology Patna on September 08, 2026, for An Apparatus For Motor Control.
Inventors include Savarn, Anurag; Verma, Vimlesh; and Anwar, Md. Nishat.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Embodiments of the present disclosure relate to an apparatus (100) for adaptive motor control. The apparatus (100) receives a direct-axis current reference and a quadrature-axis current reference for controlling a permanent magnet synchronous motor and compares the current references with corresponding feedback currents to determine respective current tracking errors. An adaptive active disturbance rejection control module (102) processes the current tracking errors, represents uncertainties affecting the respective current loops as lumped disturbances, and estimates the lumped disturbances using extended state observers. The adaptive active disturbance rejection control module (102) regulates respective ADRC system gains according to the current tracking errors and uses the regulated system gains as additional control variables in cooperation with the estimated lumped disturbances. The apparatus (100) generates voltage references, transforms the voltage references, generates switching signals, and drives the inverter controlling the permanent magnet synchronous motor.
