MOTOR DRIVING APPARATUS AND CONTROL METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106362 titled 'MOTOR DRIVING APPARATUS AND CONTROL METHOD THEREOF
Simplified Explanation
The motor driving apparatus described in the abstract is a system that controls the operation of a motor through two inverters and a controller. The controller generates a current command for the motor based on a torque command and a voltage utilization rate control value. It also determines whether to perform linearization control for the current command, adjusting the voltage utilization rate control value to linearize the current command in certain sections.
