Title: Yoshihiro Iijima and Three-Phase AC Motor Control

Introduction

Yoshihiro Iijima is an inventor associated with Nissan Motor Company Limited in Yokohama, Japan. His patent work includes a control device and method for three-phase AC induction motors.

Latest Patents

Iijima is credited with 1 patent: “Three-phase AC induction motor control device and three-phase AC induction motor control method.” The invention controls motor torque using a two-axis orthogonal coordinate system synchronized with the power supply’s angular frequency. It describes a non-interference controller that uses motor speed, a torque command, and power supply voltage to determine compensation voltages from a stored map. A magnetic-flux response filter processes the torque-axis compensation voltage, accounting for a direct transfer term and rotor magnetic-flux response delay.
