Abstract

An apparatus for driving a motor includes a plurality of neurons of neural network circuitry and motor circuitry. The plurality of neurons are configured to generate a cycle value based on a target speed, based on a speed value associated with the motor at a particular time, and based on a current value associated with the motor at the particular time. The plurality of neurons is configured to be trained to generate the cycle value to minimize an error between the cycle value and a training cycle value for each training vector of a plurality of training vectors. The apparatus is configured to have generated the plurality of training vectors. The motor circuitry is configured to control, based on the cycle value, a set of switching elements to drive the motor.
