Automated motor control

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.

What is claimed is: 
     
         1 . An apparatus comprising:
 an input configured to receive information from at least one current sensor configured to sense current in at least one current path to a permanent magnet synchronous motor;   a processing device connected to receive the information from the input regarding the current in the at least one current path and configured to send signals to control operation of the permanent magnet synchronous motor, the processing device configured to:
 receive a bandwidth value; and 
 determine at least one gain value based at least in part on the bandwidth value;
 determine operating parameters for the motor based at least in part on the at least one gain value and the information from the at least one current sensor regarding the current in the at least one current path using field oriented control by applying input-output linearization with an extended state observer feedback; 
 effect sending control signals based on the operating parameters to a control circuit to control operation of the motor.
