Title: Yutaka Kuromatsu: Innovator in Electric Motor Control Systems
Introduction
Yutaka Kuromatsu is a prominent inventor based in Toyota, Japan. He has made significant contributions to the field of electric motor control systems, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
His latest patents include a "Controller for AC Electric Motor and Electric Powered Vehicle" and a "Controller for Motor Drive Control System." The first patent involves an AC electric motor, an inverter, and a controller mounted on an electric powered vehicle. This controller features a voltage deviation calculating unit, a modulation factor calculating unit, and a mode switching determination unit. The voltage deviation calculating unit computes the voltage deviation between two voltage commands during different control methods. The modulation factor calculating unit determines the modulation factor based on the first voltage command and the voltage deviation. The mode switching determination unit assesses whether a switch from rectangular wave voltage control to pulse width modulation control is necessary based on the modulation factor.
The second patent focuses on the control of an AC motor using PWM control and rectangular-wave control. It ensures a smooth transition when switching from rectangular-wave control to PWM control by correcting the current command based on the target torque command value. This innovation allows for continuity in the current command during the transition.
