Abstract
Official abstract text for this publication.
A system and method of controlling a motor are disclosed. The system comprises a current observer for observing a motor current at a sampling rate and a proportionate-integral controller that provides a proportionate path and an integral path and at least forms part of a proportionate-integral control loop based on the motor current. The current observer observes a motor current of the motor at a sampling rate. The proportionate path calculates, for a present cycle of the sampling rate, a proportionate path term for the proportionate-integral control loop based on the motor current. The system outputs a respective motor output voltage to the motor in conformity with the proportionate path term calculated for the present cycle. In conformity with the motor current, the integral path calculates an integral path term for another respective motor output voltage to be used in a later cycle of the sampling rate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a motor, comprising: observing a motor current of the motor at a sampling rate; calculating, for a present cycle of the sampling rate, a proportionate path term for a proportionate-integral control loop based on the motor current; outputting a respective motor output voltage to the motor in conformity with the proportionate path term calculated for the present cycle; and in conformity with the motor current, calculating an integ…
