Abstract
Input-output linearization (IOL) and extended state observer (ESO) techniques are applied to a Field Oriented Control (FOC) for Permanent Magnet Synchronous Motors (PMSM). In one such approach, at least one gain value is determined based at least in part on a given bandwidth value. Operating parameters for the motor are determined based on the at least one gain value and information from a current sensor regarding motor current. Control signals used to the control the motor are determined based on the determined operating parameters. Accordingly, automated control can be effected through setting a bandwidth value through the implementation of IOL and ESO techniques.
